Hi everyone,
I'm new to this forum. Like some of you here, I also installed the trial version of Affinity Photo from their website. I installed it on Windows 10 with all the latest Windows update (including the November one). I have it on Mac too but had to check on Windows. Since everything seemed to be OK, I decided to purchase it, but on Microsoft Store. That's when I would get my first ever BSOD on my new Lenovo laptop after 3 months of smooth operating. This would happen at every launch of Affinity with the same issue related to cldflt.sys.
I deactivated cldflt.sys at system startup ("sc config cldflt start= disabled" in Command Prompt, without the quotes)
Deactivated cldflt for the current session (sc stop cldflt)
Started Affinity Photo which worked fine then.
I reactivated cldflt for the current session (if I remember well), and Affinity stayed alive.
So I reactivated cldflt for the next system startups too (sc config cldflt start= auto), rebooted Windows, launched Affinity Photo and got no more BSOD.
Note 1: be sure to have a space after the equal sign.
Note 2: you can check that cldflt is working by typing "sc qc cldflt". I could also read my OneDrive local files, so the service was working. However I cannot see cldflt listed in Services. I also checked with Sysinternals Autoruns64.exe tool, but I still couldn't see this service listed anywhere, though I now the location of the file (system32\drivers\cldflt.sys).
Note 3: maybe step 1 was superfluous, but all this worked for me, even if I am not qualified to give any explanation.
Hope that helps.
