How to fix persistent crashes in Google backup and sync? I have set up Google Backup and Sync to automatically synchronise certain folders on my iMac to Google Cloud both for backup and enabling sharing with other computers.
The process works well.
But one of the components, FinderSyncAPIExtension.appex, crashes regularly with a report containing the following:
Path:                  /Applications/Backup and Sync.app/Contents/PlugIns/FinderSyncAPIExtension.appex/Contents/MacOS/FinderSyncAPIExtension

As far as I can tell the crash is triggered every time I save a new file to a folder that is synchronised. Also, the process seems to restart as synchronisation still seems to happen but getting a crash every time I save a file is annoying.
This has persisted across multiple MacOS versions (currently on 11.1).
I doubt this is a widespread problem and might result from a clash with some other add-in or system process but I have so far found no obvious culprit.
Any suggestions as to the cause? Or how to narrow down the likely cause?
I solved this problem by turning off the option &quot;Show file sync status icons and right click menu&quot;, in Google Backup and Sync -&gt; Preferences -&gt; Settings.
