Error "Class 'JRequest' not found"

After updating from joomla 3.x to joomla 4.2.5 everything was working. I am working in phases.

So now I installed back komento I get this error:

Error "Class 'JRequest' not found"

If I look in the admin there are also a lot of errors in komento

After disabeling komento everything is back fine on my website and it is back working.

At this moment komento is disabled and I have turned off error reporting:
