2.7.2 Rev B crash on first network access after long period of idleness

[omoikane]

With 2.7.2, I am seeing a crash when entering Settings App after a long period of idleness:

--- crash at 2025/05/04 02:34:56---

I found that Settings App is not unique, for example here is a similar crash from Angle Pop:

The common theme is: after some long period of idleness (after device sync with server, perhaps), the first network access will cause a crash at pc:2408f606. With Settings App it's immediate, with Angel Pop it only happens at time of death. Demo video at Playdate Squad server:

Workaround: before playing any game, enter Settings App to get my daily crash.

OS 2.7.1 Rev B persistent and random crashes (e0)

Sorry if this is the wrong place to post this. I upgraded to 2.7.1 after seeing the prompt on my device and immediately began noticing crashes with code e0 while playing normally stable games, even navigating the device settings. Most reliably I can trigger a crash by checking for another system update, or trying to update my game library. Noticing this trend of network related activity causing crashes, I am surprised to learn that this update was meant to correct issues with opening connectio…

I have created this new thread because the old thread is marked as resolved, but it seems very similar to the old problem.

I also experience crashes when entering Settings app (most likely after period of idleness as well).
Not sure if it's related or not, but after updating to 2.7.2 the connectivity seems to be broken:

• Trying to refresh game list returns an error "Server could not be reached. Please try again later."
• "Checking for updates..." ends with "Error: Update check failed (1)" (instead of "up to date" message).
• Sometimes PD will refresh/check for updates indefinitely, without returning error.
• S1 Week 10 games didn't land on my device, though they are up on the manage page.

I move around a lot and what I've realized I have to do is manually go into settings to switch Wi-Fi networks because it will always try to connect to the one I was using previously.
