Random unwanted reset after dashboard quitting? HELP

So I’m new here, on the forums anyway. Ill tell you whats happened. I was hopping between unlimited RWD drift and C class lobbies with a few friends, you know, the usual drift missling and the occasional slow race. We searched up a RWD lobby and we got in, picked our cars etc. etc. game starts loading, Prague Reverse Full. When it had been spinning up for 5 mins we decided to dashboard and triple line button quit like a normal person would. I go to load up the game again and it says the device s full of memory, choose another device or continue without saving (it only gave me an OK option) so I hit OK. Check my cars to run a quick tune and I went from 404 cars , level 216 with 4000+ miles, max chevy and ford affinities to having 1 car (85’ Trueno, stock D307) level 216 no affinities, no drivatar records and 800000+ to my name, with no explanation. Checked my system memory, 228+ GB free. Im in a trance as of right now. Anyone else have this problem? if so perhaps a fix? sorry for it being so long.

Thanks,
