When I loaded the Minecraft launcher I keep getting a message come up everytime saying
This is an older game version that doesn't support the latest player safety features.

Yet I have uninstalled and reinstalled Minecraft to see if that might fix the problem but it has not helped at all.

If I try to play any of earlier versions ex: 1.15.2, 1.16.1, 1.16.2, I keep getting this message come up everytime:

You are about to play a version of Minecraft: Java Edition that does not support the latest player safety features.
To access these features, play a more recent version of Minecraft: Java Edition.

I understand the risk. Don't warn again about this installation.
