Huge integrity check failure after update

Hello there,
After my last upgrade from 14.0.1 to 14.0.3 i get this annoying integrity check failure.
The list is huge, i guess that a lot of files are missing.
Is it possible to fix this? Maybe by redownloading the missing files?

Here is the list:

Damn, that list is huge.
There are core files included.

Better download archive and replace files like doing an installation (config and data folder).

So you mean i should download the archive of nextcloud 14 and then just install it once again?
Would that work?
