Describe the bug
Debugging all variables does not work, when you want to debug some variables it works.

i have a new information, you have the debug problem only when the typo3 system is in the debug mode.

Sorry, but I'm unable to reconstruct this issue:

Ahh, my fault. I am able to reconstruct 😅

Okay, the issue also occures, when you try to debug {dce}.
It seems that the DebuggerUtility of TYPO3 core has issues, with static properties on PHP 8+ for persisted entities.

I've created an issue on forge for that: https://forge.typo3.org/issues/101488

Until this is fixed, you need to disable PHP warnings in TYPO3 settings, to restore debug output
