External-Sites-App breaks settingsmenu

[NextBlaubeere]

Hello,

I wanted to use the official "External Sites" App in Nextcloud which i installed via webinterface.
After that I went into Settings and played a little bit with the sites. After setting a site as visible in the "Settings Menu" when accessing the User-Settings i always get an Internal Error.
Only deactivating the App helps to resolve the problem.

Steps to reproduce

1. Install "External Sites" App
2. Add a Link as visible in "Settings Menu"
3. Click on the User-Settings again.

Expected behaviour

Normal Settings Menu should appear.

Actual behaviour

"Internal Error" Page appears.
