Android app crashes instantly in GrapheneOS

- [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 version**: GrapheneOS (Android 14)
- **ActivityWatch version**: 0.12.1b5 (33)

## Describe the bug
When opening the ActivityWatch, a white screen shows. After some time, I get the message 'ActivityWatch is not responding', leading to the error message below.

## To Reproduce
1. Open ActivityWatch app
2. Wait
3. See error

## Expected behavior
I'm new to ActivityWatch, but obviously just crashing is not the desired behavior.

## Documentation

This is the error message I got:

## Additional context

* I'm using GrapheneOS, which is a hardenend versioned of AOSP.
* I don't have Google Play Services installed, or any other Google stuff.
* This is not a one-time occurrence: the app won't start at all.
* I'm a developer (mostly .NET, though) and may be able to assist with solving this issue, although I don't know where to start.
