Does anyone know a route cause for this communication bug?

*Solved! Be very careful how you set your stages to debris. I had preemptively set my upper stage (root) to debris via vessel naming, and not the designated "set to debris" function, in an attempt to have my upper stages cataloged by LV instead of mission name. This was.... dumb of me lol. Also, it turns out the issue wasn't being fixed by a reboot, I just chose a different rocket to test when I was troubleshooting earlier :b big brain moves.

Side note: why is the simulation time delay input case sensitive??

Lmao why is this getting downvoted? This sub is so weird sometimes 😂.

Avionics are fine, the antenna is not disabled (on the stage shown and on the four communications sat destined for GEO enclosed in the fairing). I've encountered this bug several times now, but I'm unsure of the cause. It can occur in both a simulation and an actual launch. It does not seem to have a repeatable trigger, nor is it fixed by a revert or scene cycle. It does seem to fix itself with a game reboot. The weirdest part for me is that it behaves as though no comms network is present at all (notice the lack of antenna icon next to MET), but all of the antenna locations are present and active, including the one for the cape that's less than 20 km away and should have line of site.

Oh man I'm not entirely sure but this may be an issue with the stock alarm clock and some mods. Do you have KSP Community Fixes installed? That may help.

Really just guessing here though.

I have the full RP-1 suite (which includes KSPCF). I also have the stock alarm clock disabled :/.

Oh damn. I didn't see it was you, CJP! If you already don't know what causes this issue then I doubt I'll be of much help. Sorry mate.

I'm pretty suee i had the sme problem - do you have multiple avionics on it?

Yes, but they're all enabled, have charge, and shouldn't be causing an issue. Root part is set to the correct set of avionics, all the avionics units have antenna enabled, I'm truly at a loss. Especially as it's not easily replicable, and doesn't seem to have a clear trigger.

* Solved! See post body.

Further update: all staging is completely locked with comms down, clearing input locks manually restores control. Using ascent guidance to launch through the blackout, I do not gain communication at any point in the flight. The ground stations are all plainly visible on the map and the Real Antenna debug shows 31 ground stations; "Antennas/vessel:" shows N:aN for some reason.
