V2.23 working fine

Thank you for info, report has been forwarded to dev team.
Currently you can install both versions to different folders and use v2.23 as an emergency case.
You can use f.e. c:/InfinityBox/CM2MT2/ and c:/InfinityBox/CM2MT2-2.23/ for installation

Quite strange, before this case I see this kind of issues with win 7 only. It may be some kind of issue with drivers too.

Anlway wait little bit, v2.26 with many improvements is under final tests, should be released soon.

This very problem that i had on 2.24 was on Windows 10 as well. I think i still have Redmi 9A in the store so i can try tomorrow if anything changed for me on 2.25.

I encountered this particular problem (Divison by zero) only on Redmi 9A
I rolled back to version 2.23 & I'm facing this new problem..
