My iMac crashed today the Nth time. I'm not sure why and how this is happening and I'd love some help or next steps. Usually it was happening while I was using it but today it crashed just after I logged in from sleep. Any tips on how to debug this? panic(cpu 1 caller 0xffffff801aff9a25): userspace watchdog timeout: no successful checkins from com.apple.logd in 120 seconds service returned not alive with context : unresponsive dispatch queue(s): com.apple.firehose.io-wl service: com.apple.logd, total successful checkins since wake (120 seconds ago): 1, last successful checkin: 120 seconds ago service: com.apple.WindowServer, total successful checkins since wake (120 seconds ago): 2, last successful checkin: 110 seconds ago Backtrace (CPU 1), Frame : Return Address 0xffffffa13757b670 : 0xffffff8017c8e0dd 0xffffffa13757b6c0 : 0xffffff8017dd4f33 0xffffffa13757b700 : 0xffffff8017dc552a 0xffffffa13757b750 : 0xffffff8017c32a2f 0xffffffa13757b770 : 0xffffff8017c8d8fd 0xffffffa13757b890 : 0xffffff8017c8dbf3 0xffffffa13757b900 : 0xffffff801849d884 0xffffffa13757b970 : 0xffffff801aff9a25 0xffffffa13757b980 : 0xffffff801aff9660 0xffffffa13757b9a0 : 0xffffff801841e13e 0xffffffa13757b9f0 : 0xffffff801aff8a34 0xffffffa13757bb20 : 0xffffff801842837b 0xffffffa13757bc80 : 0xffffff8017d80961 0xffffffa13757bd90 : 0xffffff8017c9375d 0xffffffa13757be00 : 0xffffff8017c69cf5 0xffffffa13757be60 : 0xffffff8017c81312 0xffffffa13757bef0 : 0xffffff8017da982d 0xffffffa13757bfa0 : 0xffffff8017c33216 Kernel Extensions in backtrace: com.apple.driver.watchdog(1.0)[C29AFC04-7113-39AA-80DF-00F4DDAD0F46]@0xffffff801aff7000->0xffffff801aff9fff Process name corresponding to current thread: watchdogd Mac OS version: 20F71 Kernel version: Darwin Kernel Version 20.5.0: Sat May 8 05:10:33 PDT 2021;
