Thanks. I did delete them all (the game folder) it was working fine forever. I didn't play for a while then go to launch it and the error pops. I deleted all the game folders and tried to install it fresh. Still not working.
I checked my updates and all good. I ran SFC and DISM and no issues.
Tried disabling security (windows defender) and still no dice. What's really strange is after I attempt to run it it gets removed.
I did find this --
https://support.microsoft.com/en-us/help/2931627/error-exception-has-been-thrown-by-the-target-of-an-invocation-install
However that is not windows ten. I did find some other causes to be a port conflict sometimes during rest API calls.
It looks like the only way to maybe find out would be a modified source code with the exception catch:
https://docs.microsoft.com/en-us/dotnet/api/system.exception.innerexception?view=netcore-3.1
I also tried running the .net framework repair tool.
I also tried removing the windows features and re downloading the dot net framework for 3.5 required by the client, and 4.8.
Still same issue persists. No other apps seem to have any problems which is odd.

So it looks like it is failing to generate the hash to compare the files for validity -- or maybe it is not getting the hash.
