Repro Steps

For the past year or two, I've been using X/wslg with no problem. Starting recently, however, I observe different behavior. I'm not sure if this is from a WSL update or perhaps an Ubuntu update--I haven't changed anything else on my system that I'm aware of.

When I launch WSL2, I'm able to open X apps from the command-line without a problem. After a few minutes, though, I get Error: Can't open display: :0. Restarting WSL fixes the issue for a short while and then it reverts again.

Where can I look to narrow down the issue?

Some older postings suggest looking at firewall rules but disabling Windows Defender on the vEthernet NICs does not help, and I don't see any inbound rules for VcXsrv (nor any active VcXsrv pids).

Expected Behavior

X app should open

Actual Behavior

X app does not open
