Player crashed or hung

The player process for a world panicked, crashed, hung or exited. Play runs out of process (S5), so the editor kept running; the host restarts players from the pool and reports the fault here.

#Common causes

• A gameplay system or script panicked (the message carries the panic text when available).
• Native code faulted (access violation) in a plugin or driver.
• A system looped without yielding and the hang watchdog fired.

#Fixes

• Read the panic message and ara why evidence; fix the failing system, then press Play again.

• Run the scene headless with ara_play and ara_test to reproduce deterministically from the recorded seed and inputs.

• Check driver and validation diagnostics (ARA_GPU_*) for native faults.
