Hello, thank you for the replies.
@Dilan Rona Error still persists, but otherwise no new issues.
I have reinstalled screen to ensure that it on the most recent version. It is currently on 5.0.0-2, which is the same version as displayed on the Arch package list.
I am capable of running the screen commands on my main user and the server user. Checking the server status with "screen -ls" gives me this:
There is a screen on:
56395.vss_server (Detached)
1 Socket in /home/username/.screen.
@JakeSully Error still persists, but otherwise no new issues.
My source for dotnet 7 is a binary package available on the AUR. I swapped to the version available in Arch's "extra" repository, installing both the runtime and the SDK.
No changes. Just in case, I will mention that the version currently installed is "7.0.20.sdk120-2"
