Hi,
tried the preset live and on the image, LTSC, cannot make Qbittorrent crash on exit.
Also installed latest updates after Windows install, to see if that triggers it, no luck.
However, I used .107 as the basis, I now see you used .1.
Can you please retry, and not use any external tweaks or anything else other than the preset?
Then test pre and post Windows update, if any, to see what actually triggers it.
I'll send you latest pre-release just in case, it has a few fixes, nothing directly related.
