The system crashed because

"IOSCSIPeripheralDeviceType05::setPowerState(0xffffff804da430e0 : 0xffffff7f826f4234, 1 -> 4) timed out after 100766 ms"

It was expecting some sort of setPowerState() operation to finish, and that didn't happen within 100.766 seconds. The code treated that as a "should not happen" condition and crashed the system.

setPowerState | Apple Developer Documentation

"The driver must return IOPMAckImplied if it has complied with the request when it returns. Otherwise if it has started the process of changing power state but not finished it, the driver should return a number in microseconds which is an upper limit of the time it needs to finish. Then, when it has completed the power switch, it should call acknowledgeSetPowerState."

Perhaps this means that the OS called a driver to do a setPowerState(), the driver said things were "in progress" and promised to finish within 100 seconds, then the driver failed to get back to the OS with an acknowledgeSetPowerState() within that 100-second deadline.

19H15 is several update short of the current fully-updated version of MacOS 15 Catalina. You may find you spend your time and energy debugging a problem that has already been seen and solved.

at first blush, the references to: "IOSCSIPeripheralDevice suggests that a drive of some description is the source of your grief.
