Collabora (CODE) - Document has changed in storage

Hello,

I’m trying to use versioning on Collabora 4.0.3 and NextCloud 21. When recovering first version of document, the Collabora is stuck in the loop of “Document has changed in storage…”, see photo:

.

Any solution known? I’ve seen this issue on this forum but then I believe it was solved by upgrading CODE?

Thanks a lot!
