Hi,
thanks for the 3.7 update.
I have found out that the test host (UI version) always crashes during unit tests (automation precision) due to an access violation.
This happens with my plugins and also Steinberg examples, for both Windows and macOS versions.
The command line version (built from source) doesn’t crash.
Best,
Lorcan
