SU 2021 Will not Open - fixed

I am a novice user of SU 2018, 2020 and 2021. Until 4 days ago the software has performed well.
The issue was the SU 2021 application would go directly to Bug Splat, my solution was to delete an *.skp file in the recovered files directory, refer below for directory location
C:\Users\xxxxxxx\AppData\Local\SketchUp\SketchUp2021\SketchUp\working\SKETCHUP\RecoveredFiles
Cheers
