"SRPATH_LIBRARY" after install on clean JOOMLA4

Following error shows ON ALL pages in the backend AND frontend

I have a clean new joomla 4 website www.gemakkelijk.be .
I build everything up with the build in modules of joomla 4.
Last thing I wanted to do is add SOLIDRES. So installed component, modules en plugins.

After installing and before changing anything I get this error.
Because ALL pages in the backend shows this error I'm stuck and unable to reset anything.
WHAT TO DO?
Can't go to system, nor articles, nor modules or extentions ths error is EVERYWHERE.

Clicking on 'return to dashboard ends up on same screen with error.

If anyone can help plaese do. I'm stuck, THANKS!
