If you follow the advice and run build as root using sudo once then your obj/bin folders will be owned by root and your normal build will fail.

Please fix this properly, building should never!!! ever require admin rights, this is so very, very, very wrong.

This cache should be in a location and with permissions that non sudo users can access.

Same issue on Windows10 with .NET Core 2.2.104. I deleted the NuGetFallbackFolder then went to Windows Add/Remove Programs and clicked repair it. Well, it somehow is repaired. I checked the C:\Program Files\dotnet\sdk and the NuGetFallbackFolder is back with no error on each run now.
