Examples immediately freeze

[JoelCourtney]

Hello, I am trying to get started and I'm unable to use the examples.

1. run cargo run --release --bin all_examples2 or all_examples3
2. simulation starts and runs for a few frames (inconsistent number of frames, but always less than a second).
3. Simulation freezes and program becomes unresponsive. On macOS, the spinning ball is displayed. CPU usage is 100%.
4. Have to end process with ctrl+c.

• latest stable rust (1.72.1).
• tried on macOS (both intel and m1), and on zorin linux (AMD cpu)
• tried to run the examples on master, and at the v0.17.2 and v0.16.0 tags.

EDIT full output:

Same here, this is what the program prints:

Experiencing the same problem on Windows 10. I bisected and found for me the first broken commit seems to be c4f078daf35d093c59905860296abb2ff3655a5c, which is where bevy is updated from 0.7 to 0.8

@Ughuuu I'm not seeing a panic on my system, so it sounds like you're experiencing a different issue. I'll update my post to include the output to avoid confusion. Can you open a separate issue?

@ickk Is it panicking on your system, or freezing without any error message, or something else?

For me it just hangs indefinitely, and seems to max out a single CPU core

Sometimes it also freezes on Mac, sometimes it crashes. On windows machine I can reproduce also the freeze.

For anyone having this, until it's fixed, you can use this lock file, it works. Cargo.lock.zip

This issue can be fix by use bevy 0.11.3 refer to https://github.com/bevyengine/bevy/issues/9389 . IMHO this freeze issue can be resolve by migrate to bevy 0.11.3. And yes my macOS, Windows all freeze at start same as other ppl.

That was fixed when the testbed got updated to bevy 0.11.
