Nightly build fails to open the ROM correctly

[SergeyThePiplup]

After downloading the latest Nightly build available (from build action #6600) to test the translation, I've got the following message after opening a ROM. After that message, SkyTemple seem to react like I didn't opened anything, except I can open a debugger and edit scripts.
Platform: Windows 11.
(An error report was sent via Sentry too)

(Same error happens on the nightly from https://download.skytemple.org/skytemple/nightly too)
