I want to reinstall Unity.

Error message

When using Unity and selecting the game play button
`` All compiler errors have to be fixed before you can enter playmode! '' Is displayed
Because I didn't know how to fix it, I manually uninstalled all files from Unity.

Even if you try to reinstall it, it will always stop here (see image).
No error dialog is displayed.

* The display character is German. Excuse me.
It only says that it is being installed.

Delete all Unity and Unity Hub files below, restart your computer and download the latest software from the website

  • C:/ProgramData/Unity
  • C:/Users//AppData/Local/Unity
  • C:/Users//AppData/RoamingLocalLow/Unity
  • C:/Users//AppData/Roaming/Unity
  • UnityHubSetup.exe
Supplemental information

The current C drive capacity is 8GB. I feel like the capacity of the C drive has increased after the initial installation of Unity.
Is there a relationship? I'm wondering if there are any remaining files to erase,
Are there any other files that are saved when Unity is installed?

Despite the initial installation, the second and subsequent installations will not proceed without an error dialog, so
I am struggling very much.

I'm embarrassed with the rudimentary question, but if you have something to miss, what to do, or something you can try,
Would you please give me a professor?

Thank you.
