sounds like a sensor has burnt out or overheated, leave it to cool down and try again tomorrow would be my first approach. Next would be to start counting the cost of repairs on a day at 50kph.

Wow, that’s honest! It maybe time to really cement your memories of how much fun it must have been to whizz around at 50kph all day. You may be about to have some less happy ones. But the place to start would be to put everything back as it’s meant to be. And then, see if you can find an lbs (local bike shop) or mechanic or emtb motor repair company happy to help outside of warranty. It’s very hard to know if this will be expensive as in a new motor (expensive measured in €) or as in a second hand motor (expensive as in not knowing where it really came from and whether or not it will work for a while). Or to show whether it will be cheap as in a talented engineer replacing something you can buy for the motor (a sensor).
There are threads in this forum where motor repair difficulties with the different motors are discussed, for example the issue of calibration (search by motor type rather than frame manufacturer).
Once this is sorted, it would be interesting to hear if you plan to bypass the sensor again.
