Hello! I am having the same issue with lots of old examples and new examples. I am using a 1050 ti and the problem started after I updated my drivers a few weeks ago. I did not mind but now it is also incredibly slow on some particle effects that used to run fine. Pd I am using the steam version.
After testing it a little bit more, it just random crashes with different events.
It crashes when adding or removing particles, also crashes when changing sprites with this message:
