I started having this problem a few days ago. I’m attempting to write to a google drive folder and cannot save new files or existing files on the drive.

WriteLocalTempFileWhenSaving is set to “True” (also tried false and got same errors)
Results of Debug command TestLocalTempWriteDebug gave me: No error detected when saving
I am able to save to desktop.
