opencut_wasm_bg.js:835:17

(Note: this doesnt seem to occur in Edge, Chromium)

This happens alongwith issue #768

Expected Behavior

The project gets initiallized successfully and I get redirected to the editor.

Recurrence Probability

Sometimes

Steps To Reproduce

1. Go to the projects page (https://opencut.app/projects), and create a New project using its button OR click on a previously created project (A bad project in my case, because it never gets created.)
2. You get shown "unreachable executed" with the error in console logs SOMETIMES.

Anything else?

This was observed alongside issue #768, where screenshots are provided.
It occurred while reproducing that issue, but disappeared after a refresh and has not been consistently reproducible.

Start by reproducing the intermittent failure in Firefox on Windows and trace the initialization path shown in the stack, especially renderToCanvas, updateThumbnailFromTimeline, and loadProject. Compare the behavior with Edge or Chromium; done means creating or opening a project consistently initializes successfully and reaches the editor without the parking_lot or "unreachable executed" panic.
