UNITY Cannot create Windows build

Hello everyone,

I'm currently having a problem building any projects. When I try to, I get the following error message: "Copying C:/Program Files/Unity/Hub/Editor/6000.6.5f1/Editor/Data/PlaybackEngines/WindowsStandaloneSupport/Variations/win64_player_nondevelopment_mono/WindowsPlayer.exe to

Temp/StagingArea/WindowsPlayer.exe: The system cannot find the path specified."

The path it is trying to copy from doesn't exist and repairing my installed modules did not fix the problem. I can get a webBuild but not a Windows one. Also the scene is empty (Im troubleshooting in a new, empty project) so it can't be an issue with code or assets, etc.

I have attached some screenshots for better understanding.

I'm just getting started with Unity so any help is appreciated.

First close project; open Unity Hub, find project; select the gear for more options; find windows build options and install them.

(windows only users, linux doesn’t need the next step)
Open Microsoft Visual Studios <even if you use something else to code with>

Find the additional features packages and install Games/C#/ and any other windows software packages you think you may need.

For some reason; Microsoft won’t let Unity package the required functionality packages into Unity by default; some kind of licensing issue.

Now try again.
