I have turned off the UAC so that stopped the problem with the AutoKey to hang.

The problem with reapeaks is that I can't select a folder, it crashes (Reaper no response) directly when I select "Browse folder for ReaPeak".

I have the latest versions of Reaper & BIAB 64B installed as per date 24 Oct 2022. Windows 11. I have gone through the installation instructions and videos several times. I have BIAB installed on a separate drive K: and Reaper on C: and the both run as admin.

I can start the Reaper BIAB track injector GUI. And I have some communication between Reaper and BIAB e.g. start/stop build and create RT & RD lists.

But Reaper crashes in several cases:

1. When I am trying to send chords from Reaper to BIAB

2. Reaper also crashes when I am trying to import tracks from BIAB. A few times I have got one track imported ok (mostly the Bass track no 1). But mostly it fails even if I am trying to reproduce exactly the same steps a second time.

3. It also crashes when "Browse folder for ReaPeaks"
But I can't get any logs from this one.
