One of the third party extensions is not compatible with Joomla 5. If you can still access the backend of Joomla, turn on the option 'Debug System' in Global Configuration. The error messages will then display the name and line number of the script where the error occurs. Post the details here.
Alternatively, post the results from the Forum Post Assistant (FPA) by following the instructions at https://forumpostassistant.github.io/docs/ so that the configuration can be reviewed and the incompatible extension identified.
