Sketchup 2025 won't open

I am running a subscription copy of Sketchup Pro 2025 and have had no real issues until today. I work in multiple locations and typically have to deauthorise licences to allow me to open 2025 at home.
Today I attempted to open the sotware and although I can launch it wont open a new model or any existing files and closes without a bug splat or any other error message. I have deauthorised 2025 on all other PCs, updated graphics driver, uninstalled and reinstalled but no change. Can anyone assist?

Did you update to the 2025.0.3 release (build 25.0.660 on Win) ?

Have you opened a ticket with Support ?

Sometimes Windows traps application crashes and creates a report … see:

and:

Windows may also have created a memory dump file to go along with the report. Check:

%WinDir%/Minidump

.. and …

%LocalAppData%/CrashDumps
