Deactivated a plug in and WSOD

It looks like you’ll need to install bbPress manually: https://codex.bbpress.org/getting-started/installing-bbpress/single-site/#manual-plugin-installation

Ok, but how can i activate it when I can no longer gain access to my cp?

Hm, good point. Try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.

If that does not resolve the issue, access your server via FTP or SFTP, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue (theme functions can interfere like plugins).

That did the trick! many thanks again!

You’re welcome!
