Game constantly crashing at end or stage change of mission

I have been having the issue above occasionally for a few weeks now, but today I have been booted out and denied rewards at the end of EVERY mission I have done. I am so frustrated. I have a 2020 custom built gaming computer that can run some of the highest end games out there and honestly I am stumped and so mad. I also have no idea any other way to get support from PSO a their player support just directs to a white page and then force logs me out.

@Cookie-1 Just for clarification there is no notice or error warning, just a full crash. Occasionally I will get a "can not connect to game server" or a "game has stopped running" error but those are much more rare(but just as frustrating).
