I tried to get back into PSO2 this weekend. Last time I played was right at launch, before the English patch existed. It involved lots of trips to bumped.org for menu guides
So far, it's been a terrible experience, and I'm 99% sure it's related to Windows 10. After 10 to 30 minutes of playing, I get a crash with the message "PSO2 has stopped responding". Interestingly enough, it's happening on both my desktop and my laptop. Both were updated to Windows 10.
Here's the error in the Event viewer after the crash.

I can even boot the game, login, and just stand in the lobby and do nothing and eventually it will crash, so I don't think it's related to anything specifically done in game or related to the English patch.
I've tried using the troubleshooting tools built into PSO Tweaker, deleting my SEGA directory in My Documents, went through every troubleshooting item in PSO2 Tweaker, adding exceptions to Windows Defender for the entire folder, etc but still having the issue. Last night, I even tried a full reinstall to a different hard drive. When the install was complete I tried again to play this morning and got a crash after 15 minutes.
Some other folks on PSOWorld have reported reported similar issues. I also found
this link which has a Japanese player (if Google translate is correct) saying that Sega said all Windows 10 Gameguard issues were fixed, but in fact there are still Gameguard Windows 10 issues that are causing players to crash.
I'm getting close to just reinstalling Windows 8.1 so I can play for longer that 10 minutes.
