Sorry, I don't have access to a Windows computer, so can't really help. But it looks like you don't have any OpenGL renderer installed.

Hi, I doublechecked that I have OpenGL 4.6 installed, and OpenGL library successfully read out the version. I also reinstalled fsleyes and graphic cards driver, but the problem is still there. Could you please check if anything wrong happened?

Does glxgears work when run from within your WSL system? What does glxinfo report?
