Sketchup 2025 won't open

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:

How to detect the reason of crash? - #3 by DanRathbun
and:
SketchUp 2016 Crashing on Startup - #4 by DanRathbun

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

%WinDir%/Minidump

.. and …

%LocalAppData%/CrashDumps
