Solution 5: Reinstall the Problematic Program

Seeing the Unityplayer.dll missing error on Windows doesn’t necessarily mean a problem exists with the DLL file, there might be an issue with the program itself.

If the program or application has any kind of bug, then also you can experience this problem. So, to avoid this problem, reinstall the program.

Solution 6: Run the Antivirus Scan

In this case, you can run the antivirus scan to fix the issue. You can use Windows Defender Firewall to run the scan or it would be better to use the advanced third-party antimalware tool.
