✅ The request was aborted: a protected SSL/TLS channel could not be created

I'm trying to send a web request in .NET 4.8, but I keep getting The request was aborted: a protected SSL/TLS channel could not be created. I've did a lot of googling and people suggested all kinds of stuff, but no matter what I tried it didn't work. Here's stuff I tried:

ServicePointManager.Expect100Continue = true;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls | SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls13;
ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;

ServicePointManager.Expect100Continue = true;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls | SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls13;
ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;

I've tried various combinations of security protocols, like specifying just Tls12 which seems to fix it for some, but without any success. When accessing the URL I'm requesting in the browser and check devtools, I can see that it uses a Tls13 encryption. Not sure if that info is of any help.

Does anyone have an idea why?

COMException on Windows.Storage.Pickers.FolderPicker

I am receiving the error Error HRESULT E_FAIL has been returned from a call to a COM component when trying to run the following code:

FolderPicker fp = new FolderPicker();
InitializeWithWindow.Initialize(fp, WindowNative.GetWindowHandle(this));
StorageFolder folder = await fp.PickSingleFolderAsync();

FolderPicker fp = new FolderPicker();
InitializeWithWindow.Initialize(fp, WindowNative.GetWindowHandle(this));
StorageFolder folder = await fp.PickSingleFolderAsync();

but why does this happen? FileSavePicker and FileOpenPicker works fine for me.
