I have severe problem with Roblox

So, yesterday I tried playing Roblox. I did everything as usual - enter the website, press “play”. Then, my PC was showing everything as usual again - configuring roblox, starting, and then the loading logo disappeared and roblox did not open.
When I opened task manager, it said that Roblox game client is working and using a very tiny amount of CPU and RAM. I’ve tried everything: waiting, restarting PC, upgrading PC, reinstalling roblox. But the problem didn’t go away.

Does anybody know how do I fix it?

Guys, if anyone knows, please answer, I really don’t know how to fix it

Are you Linux?

Uhh maybe update your driver or check if there’s anything on your computer that there isn’t supposed to be. Also check if you added some type of fps unlocker as I know Roblox recently did an update

Windows. My PC is Windows 10.

Yea, before turning on roblox it updated

Also wdym by “fps unlocker”? It seems I live under a rock and do not know what is it

Then idk sorry. Roblox added the byfron anticheat to some users and it also made Roblox 64 bit

I don’t use cheats, even if I wanted to. My PC is 64 bit (I guess). Well, I’ll try some last resorts, and if it won’t work, I am gonna send message to Roblox support.
