Here is a guide that worked for me:
Im 90% sure the reason this is happening is because roblox is slowly pushing out the 64 bit client/Byfron which might be messing with a few things causing errors. This is kind of a hacky code way to do it using Tampermonkey (No, you will not get banned for this).
Hello all,
The issue mentioned in this particular thread is not related to Hyperion. However, we are in direct contact with the OP and are trying to solve the issue together. Furthermore, the method of rolling back to 32-bit as described in the above video, is not supported by Roblox, nor will it work any longer as the rollout of the 64-bit version is almost complete.
My alt is also stopped working today, it’s showing white screen
I have done the following in the video, it has temporarily worked, the white screen issue is happening again and there is no fix, please fix it asap 
Hello Lua,
Thank you for your feedback. As previously stated several times and officially announced a couple of months ago, the Windows 32-bit desktop client is being discontinued. You may be seeing the issue reappear because your client has been upgraded to the 64-bit version. Please file an official bug report to ensure that the issue is addressed as quickly as possible.
Thank you for your understanding.
