Why can't omnisharp/vscode load this sln file?

Issue Description

Trying to use vscode (with WSL remote development extention) with this project https://github.com/Azure/azure-functions-host doesn’t work

Steps to Reproduce

git clone https://github.com/Azure/azure-functions-host
cd azure-functions-host
code .

Expected Behavior

To be able to select between WebJobs.Script.Tests.E2E.sln and WebJobs.Script.sln

Actual Behavior

Only WebJobs.Script.Tests.E2E.sln works. Changing to WebJobs.Script.sln throws this error

your 131072x1 screen size is bogus. expect trouble

and nothing happens.

Deleting WebJobs.Script.Tests.E2E.sln and restarting vscode, causes it to not even recognize the project as C#. Copying all the content from WebJobs.Script.sln to WebJobs.Script.Tests.E2E.sln makes it work fine.

Logs

I don’t see any logs that seem to relate to the issue other than the screen size error mentioned above

I see this in Log (Window) output

I think I’m getting the same error in version 1.22.0.

When trying to select a project or solution in a Remote WSL accessing a WSL 2 distro I get:

Command 'OmniSharp: Select Project' resulted in an error (your 131072x1 screen size is bogus. expect trouble )

Hi… getting the same issue on 1.22.0 with Remote-WSL as @victoralvesp
