This usually indicates you’re behind on updates. Do you face any errors when running plutonium.exe? If yes, check this https://plutonium.pw/docs/update/#fixing-failed-to-check-for-updates and make sure your system clock is showing the correct time by syncing the time and date. If the error in the updater persists, could you show the error?
If you’re not facing an error in plutonium.exe, could you show the file that opens when you press Win+R and paste this %localappdata%\Plutonium\info.json and also show the plutonium.exe you’re running?
