  • If updates are available, click on the option download and install. Once the updates have been installed, restart your computer.

Clear Roblox Cache

If Roblox game files are corrupted or outdated, it may cause Roblox crashing and not launching issues. So time to time we should clear all the Roblox cache from the system to make sure that all the Roblox files are up to date.

To clear the Roblox cache, follow the steps below:

  • Exit the Roblox by opening the task manager and closing any processes running in the background.
  • Now open the Run dialogue box, by simultaneously pressing the Windows key + R key.
  • Type in “%localappdata%” (without quotation marks).

Now hit the ok button. Windows will automatically clear the things as chosen by us and once done, again launch the Roblox to fix Roblox crashing issues after the Byron update.

To download the Microsoft Store version of Roblox, open the store, and in the search box type in “Roblox” and hit the enter key.

Remove Conflicting Programs

Recently, while doing some hit and trial methods to fix Roblox crashing issues, I get to know there are programs that are conflicting with the Roblox Anticheat software and hence result in Roblox crashing issues. These programs are:

  • MSI afterburner
  • Riva Tuner (RTSS)

Both of these programs don’t let you launch the Roblox. So you need to disable both programs.

To do so, click on the start tray up arrow key, and find both programs.
