Backend error - Magento 2.4.2p1

we finished migration and we got an issue after loging to backend. I see dashboard, but I cannot handle anything (icons on the left side in admin look like inactive)

This is screen of the issue: https://prnt.sc/15pn9gk

I have Magento 2.4.2-p1

Do you have any idea how to fix it? Thank you very much.
