Minecraft Launcher (Windows 10, Java Edition) Grey Screen, Not Loading

On booting up Minecraft Launcher, the launcher window appears but remains the window remains entirely greyed out, and does not load further. 

 

Previous instances of this issue (marked as resolved) have suggested a workaround of deleting launcher_msa_credentials.json file from the .minecraft folder, however this has not resolved the issue.

 

Uninstalling and reinstalling the Minecraft launcher has also not resolved the issue.
