Local Server tests result in 279 error

[Tom_atoes]

When using the local server test feature I am recieving the following on each “clients” screen.

Expected behaviour:
This shouldn’t happen and studio local testing should launch correctly.

System Specs:
Ryzen 9 3900X
RTX 3080
32GB RAM @ 3200MHz
Windows 10 64-bit

Can you give a littlebit more information about this issue and the steps on how to replicate the issue?

I have made a post about this before but haven’t had any updates about it ever since.

Issue seems to have resolved itself, to reproduce I just started a studio test and it would consistently happen (I should have specified this in my OP, my bad).
