Problem with deck with recent update of nextcloud

[seyzed]

Hello,

We've recently updated nextcloud, we are facing issues with deck as it crashes the system (makes it unresponsive). Here is the log that causes the crash:

We've temporarily disabled the deck app. I'd appreciate if you could take a look at this, deck is very important to our business.

Was fixed in #3231 and will be part of the next release.
