I tried with a REAPER 5.22/ReaPack 1.0 portable installation in a OneDrive folder and it worked here. Some things you could try:
- Open reaper-kb.ini in a text editor after closing REAPER to see if the scripts are listed there
- Try with a new portable installation without OneDrive
Now, this is a wild guess but you do mention "all the scripts I wanted": could they be all MIDI Editor scripts?
If so, you'll find them in the MIDI Editor section of the Action List (menu at the upper right) instead of in the Main section.
