I just experienced this "socd report detected (ap watchdog expired)" on my new MBA M1 (just 14,5 weeks old) with macOS 11.5.2 installed myself. Since I had nothing connected to USB at all (this means also no WD HDD and not even a power cable was plugged in) at the moment it happened I don't believe the cause of this issue is directly related to any external devices at all. I mean it is possible that connected USB devices increase for whatever reason the probability that the error occurs, but most certainly not causing it.
Since it just happen once I have no idea how often it will happen and under witch circumstances. When it happened I had Safari 14.1.2 open and watched a YT video minimised with the picture-in-picture function while playing some Hearthstone game.
What I see with Mac Fan Control (I just use it to visualise a temperature sensor since MBA M1 has no fans) after system comes back was that the temperature of "Power Manager Die Average" was at 75 Celsius and you could also feel it that the MBA was warm (warm and not 75 C hot since I not touched the die directly within the Mac).
So maybe this is causes by a thermal issue of the M1 CPU? It was probably a bad design decision that the MAB has no fan at all since it also can become hot/warm if it uses much CPU power (I checked it in this two APP constellation is 25% of CPU power not more) for a longer period of time. If I only surf and do not play a game the die temperature is only between 35-40 C. But what is the point of have so much CPU power if you are not allowed to use it?
So I really do hope in this case it is only a software issue of macOS and not caused by any form of bad hardware design.
Within the console app in the diagnostics section I also found two identical "ResetCounter-2021-08-22-214510.diag" entries afterwards with following content:
Code:
{"bug_type":"115","timestamp":"2021-08-22 21:45:10.00 +0200","name":"Reset count","os_version":"macOS 11.5.2 (20G95)","incident_id":"PRIVAT"}

*I just replaced the Ids and Keys with PRIVAT.
When googling for "bug_type":"115" and "wdog" you found a lot about iPhone crashes.
So it could be speculate if this is neither because iPhones uses the same CPU architecture as the M1 macs or if there is a software issue within iOSSupport of macOS Big Sur (I have some iOS weather apps running on my Mac). But since it happens only on M1 Macs and not Intel Macs and it seams to happen also on iPhones it looks more like an issue related to the ARM platform.
