From ghcup tui, trying to set the ghc version fails:

Error: [GHCup-00130] The version 'ghcup' of the tool ghc is not installed.
Press enter to continue

Same GHCup-00130 error from the command line.

History: I had a previous installation of ghcup from a few years back that I tried to upgrade and it had this problem. I ran ghcup nuke, deleted c:\ghc, and reinstalled from the powershell script, and the same problem is still happening.

• The version I am trying to set is installed.
• In fact it's the only version installed, and it is currently the default ghc, although it's not listed as set in the ui
• But in my old install I was trying to upgrade ghc versions and this prevented me from changing to the new version
