NC33 fails to open the files App (spinning wheel instead of directory listings) with combination of the latest Office online Server App and nextcloud 33

Are there any files I can provide to help the triage?

[jechosu]

I wanted to add that I am experiencing this issue as well, with one of the key logs I saw displaying
"CustomMessage":"Class \"OC\\Preview\\Provider\" not found in file '/var/www/html/custom_apps/officeonline/lib/Preview/Office.php' line 17"}}

Here's a script that quickly fixes this error. It replaces entire files encoded in Base64.
