Do others have the same issue after generating a song on Reaper/ Windows 11 ?
The plugin is very convenient for Reaper , but it crashes randomly just after the generation
Loading it in a separate process as Reaper permits avoid crashing the daw (as the plugin is loaded inside the reaper_host64.exe wrapper , only reaper_host64.exe crashes) , but still it is annoying to have to reload the plugin after the crash of reaper_host64.exe
Btw , I am using the VST2 version as VST3 does not send midi program change to my synt vsti, but I have the same issue with the VST3 version.
Also , I have tried another daw (vsthost) with the same issue.
Sorry my DAW is not eligable for Win11 otherwise, the BIAB-VST has been stable with Win10.

Welcome to the forum and to Band-in-a-Box. If you would like to help PG Music resolve the issue, there are several text file logs you can copy and post in the forum.
Use Notepad to create a blank text file. Save the blank file under the name "PreserveAllFiles.txt. Move the PreserveAllFiles.txt file to the BBPlugin directory at \bb\BBPlugin\PreserveAllFiles.txt.
The blank file instructs the plugin to keep all temporary input-output files. These files normally are generated on the fly then discarded. This allows you to look and copy them.
Some of the temporary files include: BBoutput.txt RBResults.txt BBInput.txt BBSong.txt
There are two locations where you may find useful information regarding crashes. They include: \bb\Data\bbw4_PlugInLog.txt. Backend Errors messages can appear here. Backend is communication between the main Band-in-a-Box program and the plugin. \bb\Data\bbw4_64exe_FlashMessageLog.txt Flash messages are the yellow and green pop up messages that briefly appear. The Flash message file will show some error messages.
When reaper locks up, in the Task Manager you can right click reaper.exe > Create Dump file then zip it up and post in the reaper forum and they maybe able to tell you what's wrong.
You can try it in KV Element in Reaper load element as a vst3 plugin then drag and drop the BBPlugin into it, hook the in/out up then click the EXT top left to sync it.
I can not create a dump file using the Task manager as the process does not lock but die
The Windows Event Viewer mentions several files but I can not find them found errors are : 0xc0000374 , 0xc000041d , 0xc0000005 in modules "ntdll.dll" or "Band-in-a-Box DAW VST Plugin.dll"
This issue is very random , sometimes the crash happens at the first generation or after a few generations , but not always
BTW , I have the same issue with another daw (VstHost)
The plugins depend on the main Band-in-a-Box program to regenerate tracks. The bbw4_64.exe app you mentioned runs in the background as needed to provide a communication path between the plugin and the Band-in-a-Box program.
It seems that unckecking "sync" during song generation does the trick (both in Reaper and VstHost)
If checked , error happens again
(Why ? ...)
Oh, the sync button. Why didn't you mention that earlier. I think you have reinvented the wheel. I have not seen that problem in a long time. See my setup.

My point gegu was this is unforturnately old news to many of us. I set my configuration to avoid this trap. You ask why? Because even well into its 3rd year this application is a bit of a work in progress. It can work fine and do what nothing else can do, but you have to know what not to do.

The somewhat glib response points to a glaring issue with BIAB..."old hands" find & share solutions and the program isn't modified to resolve them as there's insufficient "call" to do so.
Newer users are left with the task of problem identification & solution finding or asking for help in the forum as the search engine for such issues is, at best, hopeless.
If the wheel isn't known it will, eventually, be (re)invented.

Thank you for the feedback gegu! As far as I am aware, there has never been an issue regarding the sync button causing a crash while generating, so this is not old news to me.
In order to help determine the cause of the crash, I will need you to provide me with the following files: 1. C:\Users\Public\Ticket\BBPluginDebug.txt 2. bb\BBPlugin\SavedTracks\BBInput.txt 3. bb\BBPlugin\SavedTracks\BBOutput.txt 4. bb\BBPlugin\SavedTracks\BBSong.txt
*Note that files 2, 3, and 4 require the presence of this text file: "bb\BBPlugin\PreserveAllFiles.txt". All of the files should be acquired immediately after the crash.
Could you also provide me with a saved song file (.sgu) as well as the exact steps you took to reproduce this crash? This should include details like which style/other tracks are loaded and any other information that may affect the way the song is generated.
If you have a screen recording program (like OBS which is free), it would be great if you could share a video of your screen leading up to a crash. This is often the easiest way for me to determine what the cause of the crash is.
You can upload all this information here or email me directly at aguy@pgmusic.com. I will do everything I can to help you resolve this issue!
Here is the video recording of "follow that cab" generation with "sync" checked, using vsthost64 daw and the VST2 plugin (VST3 plugin , reaper daw crash too) :
