Likely related to this:

[000000E4:] EXCEPTION handling: System.ArgumentException: 'CP1252' is not a supported encoding name. For information on defining a custom encoding, see the documentation for the Encoding.RegisterProvider method.

I revisited this after learning more about encodings, and it turns out I was completely off base. I found that there's a call to FNA3D_CreateTexture2D that never returns. We are using the OpenGL driver for FNA3D by default. I think this means the main thread got stuck doing something else.

Setting FNA3D_FORCE_DRIVER=Vulkan seems to work around this, but from what I understand there's a reason the Vulkan driver isn't the default yet, so it may lead to other problems.

[madewokherd]

The main thread isn't stuck in FNA3D code, it seems to end in a WaitHandle:Wait_internal call. So it may be that the program isn't running the main loop while it does some things in the background, but because FNA has to marshal into the main thread, those background tasks require the main thread to be running a main loop.

If that's the case, the OpenGL driver would probably have to be redesigned to marshal all calls to a thread controlled by FNA3D (not sure if that's even possible with the SDL and winforms dependencies), and the better solution is probably to wait for the Vulkan driver to become the default.
