App crashes on any page with SharedArrayBuffer support enabled

[JUSTCAMH]

To replicate:

• Open the itch app
• In the app, open any page with SharedArrayBuffer support enabled, including this one: https://terrycavanagh.itch.io/mr-platformer
• The page doesn't display correctly, everything renders grey.
• (BUG): Upon leaving the page, the app crashes. Most app-provided pages (the library, collections and dashboard) are spared from this, but any webpage will crash. Sometimes going to the browse page survives, but going to another game page (such as https://hempuli.itch.io/diagort) will definitely crash the app

The app crashes with the following warning, no other error messages seem to be logged:
