Hi I am trying to run a version of Legacy Edge that is from a Windows 10 Insider build (Build 18947.100), sadly it will not open it gives me an error saying that the app can't open

But if I try running Microsoft Edge from Windows 10 2004 (19041) the stabe build on the Windows Insider preview build (18947) edge from Build 2004 will run on build 18947

But edge from build 18947 will not run on 2004.

It appears to be an issue with the exe file from the beta everything else is fine, is it being blocked or something? I have tried many versions of Windows 10 and different versions of Edge from betas and I get the same issue every time. If anyone knows a possible fix please let me know, any help will be greatly appreciated :)
