Macbook Pro M3 Max with Dell u4025QW - Frequent Kernel Panics

I recently purchased a new 14" MacBook Pro M3 Max and simultaneously purchased a Dell U4025QW monitor. My Mac is powered by the monitor's Thunderbolt cable.

My Mac periodically restarts when left alone for long enough to go into sleep mode. I cannot figure out a pattern to it, and this happens both when no applications are open and also when many apps are left open in the background. The restart appears random ... some days, the Mac will restart each time when left alone for long periods. Other time, the Mac will run for a few days without any issue. The only thing I think (and I say "think" because I'm not 100% certain) I've determined is that the kernel panic-related restarts are associated with my Dell monitor. I believe in this correlation because over a few day period where I unplugged the Mac from the monitor whenever I would leave it long enough for the Mac to sleep, the Mac experienced no kernel panics. The absence of a restart strongly suggests that the Dell monitor is causing the kernel panics.

I contacted Dell about this issue, which began after I updated the new monitor with the latest firmware (M3T103). Dell told me that they discovered a bug in this latest firmware, and promptly sent me a replacement monitor, which has M3T102 installed. While I applaud Dell's customer service, I'm a little skeptical that they were telling me the truth since M3T103 is still posted on their website for download. Further, now with a replacement monitor running M3T102, the Kernel panics have continued.

I ran an EtreCheck Pro report, but unfortunately, the report tells me nothing other than this is likely a hardware related problem, and that the test I've already done (removing the USB-C Thunderbolt cable when the Mac is going to sleep) does appear to confirm this is a problem stemming from the connection between my Mac and the Dell.

I love this monitor ... perfect size for me. But this frequent restarting isn't sustainable. I've only had the computer and monitor for about six weeks and I'd say I've experienced this issue more than a dozen times already.

Anything someone can suggest?

Much appreciated.
