@ismcagdas , I had probably a similar problem, and didn't know why the powertools just didn't do anything. Of course the .net Core 2.2 Runtime was missing. But I only found out after trying to call the Powertools from the commandline. Maybe you could make a sanity check for the Power Tools in the UI whether all requirements are correctly installed, or at least leave the command window open after completion if there was an error executing, that would help immensely because the error message would have said right away that the runtime was missing.
Or as a final suggestion, just update it to a runtime (e.g. 6? ;)) which is definitely installed along with the Visual Studio version you require anyways, that would save the most trouble ;).
