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

SDK Bug Reports

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:

--- crash at 2025/05/03 22:55:38---

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.

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.

I tried several networks (different ISPs, landline and mobile), didn't help.
Strangely enough, haven't been experiencing any crashes since my last message.

I am still getting those crashes at pc:2408f606, although they are not necessarily once a day anymore. Demo: Playdate crash · GitHub

For variety, this time I ran Root Bear. Previously it was Angel Pop and Settings App, basically anything with network access.

I haven't seen another crash of this sort ever since upgrading to 2.7.3.

Well, that's strange.
I've updated to 2.7.3, didn't help. Then i downgraded to 2.6.2, and it didn't help either.
Then i turned Playdate off and put it away for several days, and tried updating to 2.7.3 once again, and suddenly network problems are no more.
