[Bug]: App not loading on mobile / Safari iOS

### Verified issue does not already exist?

- [X] I have searched and found no existing issue
- [X] I will be providing steps how to reproduce the bug (in most cases this will also mean uploading a demo budget file)

### What happened?

The app does not load on Safari mobile iOS 15.8.3. Running actual v24.10.0. I have confirmed that the same error occurs on the demo site and is most likely not caused by my setup.

Error on 24.10.

----

I have also tested actual 24.8 (https://deploy-preview-3179.demo.actualbudget.org/) which is working, while 24.9 (https://deploy-preview-3348.demo.actualbudget.org/) shows a different error than 24.10 but is also broken.

Error on 24.9.

Thank you!
