Since updating Band-in-a-Box 2020 on Windows 10 HE 64-bit to version 721, the VST3 crashes in both Studio One 4 Pro and Cakewalk by Bandlab. I think I have narrowed the culprit down to Malwarebytes Pro, as with that program switched off, the VST3 works perfectly. I added the bbw exe files to the Allow list in Malwarebytes, but to no avail. The DAW Drag and Drop feature is not affected, just the VST3 app.

For those of you who can make sense of such things (I can't), here are a couple of error messages from today (full error logs available if required):

Exception class: EFOpenError
Exception message: Cannot open file "C:\bb\Preferences\DXiPluginListX64.ini". The process cannot access the file because it is being used by another process.
Exception address: 000000000052501A

Exception class: EFCreateError
Exception message: Cannot create file "C:\bb\Data\bbw4_PlugInLog.txt". The process cannot access the file because it is being used by another process.
Exception address: 0000000000524F81

Best,
