Error retrieving certificates from Azure Key Vault

When retrieving certificates from Azure Key Vault I get the following error in my .NET Core 3.1 app service.  The file is read from the Key Vault just fine, but throws an exception when converting the secret to a x509 certificate:

Internal.Cryptography.CryptoThrowHelper+WindowsCryptographicException at Internal.Cryptography.Pal.StorePal.FromBlobOrFile

VERY Slow Windows 10 Right Click

For a while now whenever I R-click in my Windows 10 File Explorer the system hangs for about 10 seconds and then finally responds.  I've cleaned out a few of the programs that show up in the context menu, but no luck.  I just found this article, which sounds promising.

Awesome!! This worked.  Following these steps and running ShellXView to see the context menu programs was VERY eye opening.  There are about 40 programs using the context menu.  In my case it was TortoiseGit that was slowing me down.  Once I realized that it was the culprit, I uninstalled it (since I no longer need it) and now my life is 1000% times better.  R-click is lightning fast again.
