flexicontent - admin configuration broken - error 0 / jQuery is not defined

dear flexicontent team,
i have updated a joomla 3 to joomla 4, the site works well, only the backend has some issues.
when i want to edit the flexicontent configuration, i get a "broken page".
the html-titel is "fehler:0" (error:0) and devtools displays following error:

my site is using php8.0
joomla 4.2.9 - flexicontent 4.1.5

lookg forward for your feedback,
best,
bart

maybe you have WAF protector in your server, try to desactived it or check log error

sorry i forgot actived debug mode in joomla

good point to activate the debug-mode, also for the administrator area.
i got more detailed error now,

error - Uncaught Throwable of type ArgumentCountError thrown with message "3 arguments are required,...

will do some more research later and give feedback.
thanks already
