Description

Steps to reproduce the behavior:

  1. Extract the windows build zip from the releases tab to a desktop folder that is redirected to a UNC path fileshare folder.
  2. Run the .exe
  3. The application will launch, but instead of loading into the interface it will show "This page isn't working right now".

This may be related to the length of the path instead of the path being a UNC path.

Expected behavior: The program works normally.

Screenshots: image

Platform: Windows 10

Additional context: The application works fine once moved to the C:\ drive or outside of a UNC path.

Research direction
Investigate the root cause of the error when the app is launched from a UNC path. Check the Electron main process file (likely `src/main.ts`) for how the app's file path is resolved. Compare behavior when run from C: drive vs UNC path. Consider using `path.resolve` or handling `process.cwd()` correctly. Look for any existing workarounds or similar issues in the repository.
