I accidentally left my truck on "Other jobs" while taking my 45 hour break

I took out my card at 2:05 AM but accidentally left it on "Other work" and Monday I started and drove away and realised at my 45 minutes break that I fucked big time. Called my boss told him everything and he told me to take a week off and figure this out. Now, if I start driving in Germany and BALM or BAAG stop me, how do I get out of this without getting fined very heavy.

The card was taken out, the truck wasn't driven by anyone in that period I had my pause at home.

Yeah, im new still figuring it out
