Unfortunately yes, a month or so Roblox actively blocked Linux än VM:s. They claimed it is only temporarily until their new client is stable so that they can evaluate the results for windows first. General consensus seems to be that could just as well just filtered the results considering that they are able to block Linux all together.

I haven't checked it out for a couple of weeks though so I don't know if a workaround has been found. It's annoying though because Roblox worked perfectly before that. I would have loved to migrate my kids computer's to Linux as well since I got problems with rage every time I try to fix things on them 😅
