Backtrace is pretty consistent, fault address is always 0x58, and instruction
is:

movl 0x58(%eax),%eax

with eax = 0x0

It would be better you attach the full console output instead.

console output

Console output is attached.

I recompiled wine with debug symbols, but unfortunately backtrace doesn't
improve.

I did some testing, and it actually works fine with DPI from 96 till 143. But
it crashes with DPI = 144 and over. Does it ring any bell?

Yes, Guitar Pro 7.5 (and 7.6) works fine on Windows 10 with HiDPI screen.
