qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.

- [ x ] I am on the [latest](https://github.com/ActivityWatch/activitywatch/releases/latest) ActivityWatch version.
- [ x ] I have searched the issues of this repo and believe that this is not a duplicate.

- **OS name and version**: Debian variant (corporate)
- **ActivityWatch version**: v0.12.3b10

## Describe the bug

I just updated to https://github.com/ActivityWatch/activitywatch/releases/tag/v0.12.3b10 because of https://github.com/ActivityWatch/aw-watcher-window/issues/89 and now I do not see the aw tray icon when starting up. I think this may be a dupe of https://github.com/ActivityWatch/activitywatch/issues/660, but i do not see the offending library in my install directory.
