I found that the activity app was the reason of such behavior. I'll open issue on app's page.

please tell me the link to your issue on app's page
i have same problems

[massa007]

That solved the issue while creating files/folders but I´m still not able to delete/modify anything!
Is this only me? (same error code)

[jessrbird]

I've noticed the same thing as massa007. Deactivate activity app helps, but still unable to delete/modify. If I try to upload a file with the same name, I get the "1 file conflict" message, I choose to "have a number added" to the new file and click continue. It goes through the upload process, then fails with unknown error and "Error: Call to a member function getUID() on null" in the logs.
