Latitude 7430 Random Restarts/Shutdowns

We are experiencing an issue with nearly all Latitude 7430s that we have deployed recently. When purchased, they were Win10 though some of them we upgraded to Win11 through Windows 11 Installation Assistant. These laptops are joined to a domain. 

The issue is that they are crashing seemingly at random, but regularly. At least once a day in the normal course of work. A slight pattern may indicate that it happens more often first thing in the morning when the laptops are plugged into Dell docking stations. That said, it also happens throughout the day without any obvious action by users. 

When the laptops that have been upgraded to Win11 experience this issue, they restart automatically, and the Windows recovery screen appears. When choosing to restart on that screen, the laptops reboot into Windows without issue. 

When the Win10 laptops experience the issue, they restart but boot directly into Windows without the recovery screen. 

Event viewer shows a Kernel-Power critical event "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly" but only 0 for the bug check information. There is also an 'Error' entry stating the previous system shutdown was unexpected, but the time it states that this happened is often not correct. 

We have Sophos and ManageEngine Agent, Office, Teams installed on these laptops but minimal other software. Laptops are up to date according to Dell-Command Update and Windows update. Support Assist does not detect any issues. 

Any help identifying what might be causing this is very greatly appreciated. If I can provide any additional information, please let me know.
