BUG REPORT: no preview in After Effects 2021 after wake-up

Question

After Effects will not preview any comps after sleeping. When I hit play, or the spacebar, even if I change the shortcut to something else as another post suggested, it doesn't play. The green line indicating render fills the whole comp, any comp, but even then it doesn't play.

This problem seemingly happens after any time the computer goes to sleep. The only workaround is quitting After Effects and re-opening it. Once I restart the app it plays fine.

This issue only seems to happen if the system fully goes to sleep but not if just the display is turning off. If I manually press sleep and don't leave it sleeping for very long on wake it can still play, but if I wait too long the bug persists.

Adobe After Effects 18.2 (2021) no plugins.

One more note on this, if I'm waiting for too long for my comp to finish rendering and my screen goes black while the preview render is happening then the bug starts to happen as well, so the whole system doesn't necessarily need to be on sleep mode for the bug to happen.
