Describe the Bug

Recognize finished its run and I do see in the Photo app the persons (without assigned names).
Clicking on the person shows the detected photos.
I use the Edit persons name (little PEN on the right upper screen) and assign a dedicated name.
After that I only see a grey exclamation mark then I click on the persons picture in the general overview mode.

Expected Behavior

Clicking on the persons picture to enter the overview of all their detected pictures should display the pictures as it did before.

To Reproduce

1. Select photos app
2. Select Persons
3. Click on one of the persons faces in the general overview
4. Click in the upper right on the Edit Symbol (little pen shown)
5. Enter a new name

Instantly after ways a grey exclamation mark symbol is shown and starting from that point it is not possible to see the detected pictures of that person.

Hello 👋

Thank you for taking the time to open this issue with recognize. I know it's frustrating when software

Thus, if you can, you could also look at other issues to see whether you can help other people with your knowledge

Update:
I forgot to mention that my server is using coreruleset 4.8.0 as a security filter.
As there are rules defined for the Nextcloud recognize app I thought that it is not important.

However, after further investigation I figured that without coreruleset the recognize app seems to work correctly.
It seems to me as if the coreruleset rule for Nextcloud only allows to use numbers.
Unfortunately I could not yet figure out how to modify the rule so that it is allowed.
