Nextcloud Office do not work under NC27

i got a update to Version 27. Now my Nextcloud office 8.1.0. “Nextcloud office cannot be started”

What can be the reason?

Since you didn’t fill out the support template nor provided any information about your setup, nobody here will be able to help you.
(Example: My car is broken, what could it be?)

Have you already used the search function:

Much luck!

Sometimes it might help, to mark the item “Use embedded CODE - Collabora Online Development Edition” one more time (even it is marked) until “Settings saved” appears in the upper right corner.
(I need to do that after every startup of my Nextcloud server.)
