Sketchup 2025 turns off after I chose a File or a Template. The Startscreen opens. I have the latest graphic Driver, I installed Sketchup as Admin, rebooted several times.
Copy: %AppData%/SketchUp/SketchUp 2025/ and paste it into File Explorer. Find the file called login_session.dat and delete it. Then do a cold reboot of your computer and try opening SketchUp again.
Note that there have been reports that the license server has been down for maintenance. If it still is when you do this you may need to wait until it’s back up to sign in.
