Have you scanned with any malware scanners to see if malware has compromised your system? Recommended scanners are Malwarebytes (Free version) & AdwCleaner.

If no malware is detected, suggest you run a SFC to check if any of your files are corrupted/can be repaired. Option 3 is recommended.

SFC Command - Run in Windows 10 - Windows 10 Forums



Note If SFC could not fix something, then run the command again to see if it may be able to the next time. Sometimes it may take running the sfc /scannow command up to 3 times with restarting the computer after each time to completely fix everything that it's able to.

If not, then run the Dism /Online /Cleanup-Image /RestoreHealth command to repair any component store corruption, restart the PC afterwards, and try the sfc /scannow command again.

If still not, then do a system restore using a restore point dated before the bad system file occurred to fix it. You may need to repeat doing a system restore until you find a older restore point that may work.

If still not, then you could do a repair install without losing anything.

If still not, then you could refresh Windows 10.
