Error 500 on Nextcloud 21

When I click on 'extract here', no matter which format, the extraction fails. Running in a docker container. No server-side encryption. p7zip, p7zip-full, and unrar are installed correctly. I would be much appreciated if you could help me on this. Thanks.

Same issue here. Clean install, all librarys installed, php shell_exec function is allowed and file is not damaged. Seems to be a bug on app-side.
