BSOD with Windows 11 Portable 1.26.27 version

[Tiry]

Hi everyone,

The latest version (1.26.27 portable) causes a BSOD on Windows 11.
The bug systematically appears when mounting a disk
This BSOD isn't uncommon: when mounting a drive, it simply crashes about half the time.

The problem is that I didn't have any logs to provide: I just got a green screen.

The previous version (1.26.24) also had this issue, but a BSOD bug is supposed to be fixed in version 1.26.27.

But after persisting, I managed to get a dump file.
So I'll try to help you, but I'm not an expert.
I just followed what Gabriel Nilam do in the other thread .

I ran the analysis on WinWdb.
I'm just putting everything here. I only deleted part of the context (I don't know if it contained private information; I'll provide it if necessary).

Thanks
