Game keeps crashing while playing minecraft server and doesn't send report to crash report folder

Whenever I'm trying to play a competitive server or just any other server my game crashed mid fight or something important. It's been doing this for the past 48 hours. And it doesn't send a report to the crash report folder in the .minecraft folder. So please respond and try to fix this. It the new launcher and my friends also are having the same issue with this. So please try and reply soon because I don't know what to do and it's very irritating and annoying. Thank you for reading.
