This clears the Microsoft Store cache.
9. Reinstall Roblox

If Roblox is still not opening:
Right-click Roblox shortcut → Properties.
Go to Compatibility tab.

Advanced Fixes
If Roblox still refuses to open, try these advanced methods:

Install and restart your PC.
14. Check for Corrupt System Files
Use System File Checker (SFC) to repair missing or corrupt files.
