Bumping this bug report a bit more after a while, but Roblox should look into what Windows on ARM uses for emulation. From what I read here: Port Studio to ARM64 WIndows - #11 by pobammer
Roblox should not entirely disable emulation, as Windows Prism is used to emulate x64 applications onto ARM64 devices. That’s how Roblox was usable on ARM. Hopefully they can whitelist Windows Prism for Roblox to work.
