So what am I supposed to do now, I asked for help lol
It needs to be fixed by some one doing VESC repairs.
You could take the PCB out of the housing and inspect it visually.
Sometimes it is possible to see physical damage.

DRV dsnt always physically show its done. Since your 5V rail is fine, its at least not dead. My bet are on borked DRV, coldsolder joint somewhere near it or a FET went byebye

Wait ur right, I was in @pjotr47 thread from a while back and it should be there
Pic from his thread
This looks fine, you can see the gold plating.
Either something is wrong with the DRV or something on the voltage divider or the shunt amplifiers.
Could also be a Mosfet.

Lol I’m with @Trampa on this one, hardware vendor cannot be held accountable for users installing untested firmware.
Its like me expecting Del to have tested my Windows pre-installed for running Ubuntu.
Can’t say it’s up to the software guys to make sure it works for all hardware when talking VESC tool then say it’s up to the hardware guys to make sure all software works LOL

I agree with this.
The truth is any vesc based esc can fail due to a multitude of reasons not always apparent.
I had a VESC6+ go poof due to internal motor shorts that did not always occur.
I was lucky I found the problem as it would lead to a non stop vesc failure from time to time.
It is very difficult for the end user as well as the manufacturer to know where the fault lies apart from the odd cold solder etc.

Intermittent motor shorts are one of the worst things to spot. Same goes for intermittent sensor issues or switches/BMSs that cut power randomly.
