Unity2019.4 going to "Not Responding" for a few seconds when Play Mode is started

how do I fix Unity 2019.4 “Not Responding” for a few seconds everytime the Play Mode is started? Literally even with just the default scene that has a single camera and a light

Entering playmode causes a domain reload. This may take a varying amount of time. Prior to Unity 2020 there was no progress bar shown and it may appear as if the editor is frozen. Possibly the same when making builds.

You should consider upgrading since 2019 is pretty old and doesn’t have the disable domain reload (2021 onwards) setting which effectively makes entering playmode nearly instant with relatively little extra work.
