Error: Hash does not validate

[Lemmork]

If I click on the "Create new" or "Create new relation" button to add a video to the frontend-plugin. I get an "Error 500".
Taking a deeper look into the logs it says:
Core: Exception handler (WEB): Uncaught TYPO3 Exception: #1489751363: Hash does not validate | RuntimeException thrown in file /var/www/html/Packages/Libraries/typo3/cms/typo3/sysext/backend/Classes/Controller/FormInlineAjaxController.php in line 750.

Any hints on this?

TYPO3: 8.7.4
html4videoplayer: 7.0.1

Hmmm... looks strange. I don't know... do you have some deeper debug information?

[Lemmork]

Unfortunately not.
I tried to debug the hash-calculation, but did not find strange things.
You can reproduce it with the typo3 docker image (https://github.com/martin-helmich/docker-typo3).

Works fine with 7.6.

I created a pull request for this issue. Apparently the values in enableControls have to be set in TYPO3 8.
