Did you try to downgrade back to previous version?

I had the same issue coming up out of the blue in version 1.78
Seems the 4th byte of the cycle_capacity field ( buf[189] ) is set to 0x2 in my case.
Looks like this byte value is slowly increasing...

This change fixed the issue for me:
is_new_11fw = buf[189] in {0x0, 0x1, 0x2} and buf[189 + 32] > 0 # 32 cell version

The problem in the latest version is displaying the wrong battery percentage. It went up to 160000. I had to roll back to version 1.79
