TYPO3: local ddev installation is working, deploy on server not -> white screen

I've got a local TYPO3 11.5.x ddev intallation which is working fine. I transferred the project via deployer and bitbucket pipeline to my server. There I have a symlink which is pointing to the current release and the domain is pointing in the public folder of the current release. Unfortunately I always get a white screen on firefox and a 500er error message on chrome.

I already activated error display and got this error display:

I have really no clue what that could mean and would appreciate any help.

Thanks, Mylene

The error message states that there is a problem with at least one folder.

You can go to the install tool / admin tools: Environment -> Directory Status and try to create all necessary folders.

If this does not work you may need to correct the rights by hand.
Have a look at the commands chmod and chown from your server.
