Bug: FluentAuth and LearnDash leads to strange behaviour when viewing / editing posts or pages

[skilldrops]

I have installed FluentAuth and I found out, that the combination of FluentAuth with Learndash leads to strange behaviour.
After installing FluentAuth I wanted to edit a post or a page in admin area. Then a white page with an error message appears.

Message:
There has been a critical error on this website. Please check your site admin email inbox for instructions.

This is my environment:
WordPress-Version 6.1.1
Active Theme: BuddyBoss Theme (Version 2.2.1.2)
Actual Plugin: LearnDash LMS (Version 4.4.1.2)
PHP-Version 8.0.15

What I have tried:

1. I uninstall LearnDash. FluentAuth is still activated. I try to edit a post or a page in the admin view. No errors. It works fine.
2. I uninstall FluentAuth. LearnDash is still activated. I try to edit a post or a page in the admin view. No errors. It works fine.
3. Both plugins are installed and activated. I try to edit a post or a page in the admin view. The error happened again.
4. In the FluentAuth security settings I unchecked all settings. I try to edit a post or a page in the admin view. It had no effect. The error happened again.

Then I receive an email with the following informations:
