We are using following image:

 mcr.microsoft.com/windows/servercore:ltsc2019 

We are using a machine that was created from above image. On this machine, we are attempting to run a restore operation, but we are encountering the error mentioned above.

Additionally, I can confirm that the following is also installed on the machine:

  --add Microsoft.VisualStudio.Workload.NetWeb`;includeRecommended `
        --add Microsoft.VisualStudio.Workload.Azure`;includeRecommended `
        --add Microsoft.VisualStudio.Workload.Data`;includeRecommended `
        --add Microsoft.VisualStudio.Workload.ManagedDesktop`;includeRecommended `
        --add Microsoft.VisualStudio.Workload.Node`;includeRecommended `
        --add Microsoft.VisualStudio.Workload.Python`;includeRecommended `
        --add Microsoft.Net.Component.4.5.2.TargetingPack `
        --quiet `

so please suggest what is causing the issue?
