Yes, the crash was to be expected. This was to let the dynamic linker talk about its doing.

First info: LyX is using the bundled Qt5 frameworks.
Second info: Qt loads libqmacstyle.dylib just before the crash.

So, probably it is a problem in Qt indeed. 
At the moment I have to look into the Qt source to get an idea how to improve the situation.

Here it is working on macOS 11.7 and on Johns machine it runs fine too - so there is some hope :)

Do you have any Qt related environment variables set?

BR, Stephan
