Can’t Upload to Google Drive Without Hanging

UpdraftPlus worked perfectly up until about a week ago with copying the backup to Google Drive. All of a sudden, it would hang in the middle of uploading the ZIP files. No plugins have been updated on my WP site. I have done a few tests:

– Uninstalled/reinstalled UpdraftPlus (did not wipe settings, though)
– Switched to Dropbox for remote storage; this works perfectly, no problems
– De-authorized UpdraftPlus with Google and re-authorized
– Changed the split from 400mb to 100mb
– No problem backing up and copying just the databases; it is when I do both files AND databases the copying to Google Drive hangs.

Here is the last part of the log file:
