Hello!
Sorry for the double post, I now found the longer thread I was looking for:
I use this older threat, as the issue is the same and loads of users are experiencing exactly this problem.
Until now, all admins replied, that the problem could not be reproduced - I can now tell you what causes it but not how to solve it.
Everytime I use a big airport in MSFS 2020 for example EGLL oder KLAX (both Asobo) with many sim objects (obiously more than the magic 1000 sim objects) and switch to VR, the toolbar cannot be opened anymore and the sim will hang up when trying to return to main menu, Couatl restart not possible in the most cases, and if a restart happens, no difference in the behaviour.
This is easy to reproduce.
GSX deavtivated -> problem "solved"
None of the tips in the manual (page 97 and following pages) made a difference.
Any solutions or suggestions?
Best regards!
Christoph
