Comfy Desktop.exe doesn't start at all after last update

[tankist-git-2]

27.08.2026 I used Comfy Desktop well, but next day (28.08.26) I tried to start Comfy Desktop again and got the message:

After this, the following window is displayed for a very short time:

After 2 seconds, the window closes and nothing else happens. The СomfyUI process is not listed in Task Manager. When I restart ComfyUI again, the same thing happens, and I can't launch ComfyUI at all. What should I do?

Windows 10.

I have the same issue

I had no idea how to fix it, so I completely removed ComfyUI directory and installed new version instead. The directory with my old settings was adopted normally.

Exact same issue here but on windows 11
