empty window for `dotnet new photinoapp` on `Ubuntu 22.04.2 LTS`

[BryanWilhite]

i went through the normal dotnet new photinoapp -o MyPhotinoApp\ into and am seeing this:

there is some symbol lookup error:

/usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/WebKitWebProcess: symbol lookup error: /snap/core20/current/lib/x86_64-linux-gnu/libpthread.so.0: undefined symbol: __libc_pthread_init, version GLIBC_PRIVATE

@BryanWilhite Would you mind right-clicking on the webview, opening Dev Tools and seeing if there are any errors shown in the console? Also open the Network tab in Dev Tools, refresh the page and see if there are any errors retrieving files. Thanks!

Also, it looks like installing VS Code via snap sometimes messes up the path to GTK. See if this post fixes it for you. https://stackoverflow.com/questions/75921414/java-symbol-lookup-error-snap-core20-current-lib-x86-64-linux-gnu-libpthread/75956168#75956168

Historically, installing VS Code via snap didn't even work and it appears to still be problematic. We recommend downloading an installing it manually. There are instructions on the VS Code web site.

@MikeYeager there is no right-click context menu appearing here:

But, yes, I have installed VSCode via snap. I had to uninstall my Obsidian snap because it caused amdgpu crashes that took down the whole desktop. So it makes sense to me that the VSCode snap would have/cause problems.

Sorry about the confusion @MikeYeager: Photino runs fine outside of the VSCode terminal:

You already know that the VSCode terminal is an environment that is not same as my local desktop/terminal environment.
