    Looks like it may have something to do with PHP 7.4.7 I went back to PHP 7.3.19 and did not get that error.

    I can confirm this bug. I have the same error using the docker image with PHP 7.4.7.

    @axheli I do have these errors in the log as well.

    And also in the client
    image

    But it doesn't seem to affect Nextcloud beyond these errors.
    Everythings gets deleted fine, and uploaded fine.
    Or did I miss something?

    @AndyXheli I am no longer using the encryption app (I disabled it) and I do no longer support any code I wrote including #24966. Maybe someone else can help you.

    I have just updated to 21.0.3
    And the file Encryption.php hasn't changed since @jknockaert fix.
    There's just some additional comments, that's all.
    So the fix should still work.
    I'm applying it, and we will see

    Seems like this patch is live on version 21.0.5
    Which is kinda weird as I don't remember seeing this in the changelog https://nextcloud.com/changelog#21-0-5
