I'm sorry that you are experiencing this issue, and thank you for reporting.
I noticed in the video that you have a drone deployed. Having a drone deployed on servers and in p2p mp will cause several issues, including extremely high ping in A20.4 b42.
There will be a fix for this issue in A20.5.
The issue you are having is most likely due to the drone, but if you still have them in A20.5, please let us know.
