[Canary] Theme Studio "failed to start properly"

(#3618) Bug Confirmed Priority: P2 desktop
by Mon

Observed behaviour

When trying to open theme studio i got the following error window "Fluxer failed to start properly. This could be due to corrupted data or a temporary issue." I expected the window to just be theme studio. It's possible to get past the window by clicking "reset app data"

Reproduction steps

  1. Click "Open theme studio..."
  2. Error window appears.
