I find this extremely hard to believe.
I use Windows 11 currently, and have never had issues with any of the ROBLOX products prior to the implementation of the 64bit client and Hyperion. However, as of recent, I have had more crashes in the past 2 months than prior since 2014.
I would also like to implement that my friend, who usually used Linux, has switched to Windows for ROBLOX lately.
I can attest that when playing games, he crashes nearly 1/2 of the time joining into a new game, despite not changing nearly anything from out of the box Windows 11.
It’s really frustrating playing a game and being booted out as soon as it teleports you to another place.
