For some reason NDecrypt v0.3.2 is crashing on my machine when I try to run it.

I was able to resolve this issue by running a simple PowerShell command, which I found on stack overflow.

Set-ProcessMitigation -Name NDecrypt.exe -Disable UserShadowStack

but I just wanted to make you aware of this in case you know of something which can be done to ensure better compatibility out-of-the-box.

I'm on Windows 10 21H2 (19044.1288) with an Intel i5-12500 CPU and 96 GB RAM.

I have never seen this error before in my life and feels like a Windows issue more than something that I can actually do anything about. I'll consider seeing what could actually be done, but this may be a "close as won't do" scenario.
