3D Slicer Does Not Open

I’d like to ask why I cannot open the 3D slicer. Until yesterday I was working normally. Today I’m trying to open it and the program does not correspond at all. I added some extentions lately but I restarted the software as it mentioned and the program operated normally.
Any ideas?
Thank you.

Probably your settings have become corrupted (because of instability caused by an extension, incorrect application shutdown due to multiple monitors, sleep mode, etc.). See troubleshooting instructions here.
