Brave looses all added plugins when starting MacOS in TargetDisk mode

When I start my macbook pro in Target Disk mode and start macOS connected to my Mac Pro Brave looses all plugins. All websites and bookmarks are still there, but the plugins are gone. When I restart my macbook normally the plugins are also gone and need to be reinstalled.

Please advise how to fix this. A similar thing use to happen in Chrome, but as soon as you would sign in to google, chrome would repopulate the plugins.
