Car suddenly turns off ABS, TCS, powersteering, ESC

[Leon1810]

Hi guys!
(It‘s my first thread here so I hope I‘m bot doing anything wrong)
So today I came up with the idea to take my Seat Ibiza Mk6 for a little spin in the snow what turned out to be a bad idea. I ways going up a hill and it was a pretty snowy road so I had to turn off the ASR so I wouldn‘t get stuck. I went up there but suddenly, I had a speedometer that was lighting up like a christmastree. Everything deactivated itself, ABS, ESC, ASR, Powesteering and all the stuff you usually have in a modern car (and my speed was also constantly at 0). When I stopped the car, it wouldn‘t take any throttle anymore because of the red brake light.
Has anyone had the same problem, or any guesses what the problem could might be?

Merry Christmas and a great week ahead!

Update: In the morning the car still showed me the same errors. I then decided to drive the car down the road by playing around with the clutch and suddenly all errors disappeared and everything worked again.
