Return of Reckoning

Hello,
So i play RoR for 2-3 months now and just now 10minutes ago mmy game window closed just when i was running around in altdorf or when i was in sc.
Just the window closing without anny message or error.
I never had this before and ive bbbeen playing now since last night without anny problems until now.
Someone has this same exact problem or can help me try to fix it?

Thanks upfront

I still have this sometimes, annyway know why this happenes|?

There is probably no way to know why this happens. Every device connecting to the servers is bound to have it's own problems. We do the best that we can to address them, but the client crashing with no error message or apparent cause is not something you'll find people volunteering to do a root cause analysis on.

IRL, I'm a sysadmin. When someones browser window/app crashes "for no reason", we kindly suggest they open a new instance and proceed. Find a reason, and we then have something to work with.
