Siril will not install on WIN 11 pc

Hi

Specs first
Win 11 OS
16gb ram
SSD
downloading version 1.2.6

Initially, I get a message from Windows Defender saying the download link is not safe however I over-ride that and run the .exe installer.

After installing, Siril opens but I immediately get error messages all related to Gtk drawing failure errors and the program will not run. I’ve copied the log below.

The errors comes from your side because Siril can install without issue on Windows.
Make sure your AV did not removed any important files.
