last few weeks were rough, yesterday this issue also prevented me from sending jobs to the render farm. I was up till 2:00 AM uninstalling and reinstalling max didn't help. I have to finish 3 projects by mid next week. why is this happening? so no fix to 8.2? why?
I don't know if it will help you, but someone said that assigning a different renderer in Render Setup and then switching back to Corona will avoid the crash. Need to do it every time you restart Max, or assign a different default renderer. Hope that can help!
Then you can try to put this in script/startup folder.
Either
C:\Program Files\Autodesk\3ds Max 2023\scripts\Startup
or
C:\Users\[username]\AppData\Local\Autodesk\3dsMax\2023 - 64bit\ENU\scripts\startup
just save any .ms file something like "coronafix,ms"
renderers.current = DefaultScanlineRenderer()
renderers.current = CoronaRenderer()
