MBP 15in 2018 keeps restarting when going to sleep

Laptop keeps restarting when I wake it from sleep. This is the error report I am getting:

You are not alone. A lot of users have been experiencing the "watchdog timeout" panic, some related to waking from sleep


See the following threads. You can save some time by jumping to the end of the threads, as that is where some of the users are finding ways to mitigate their situation.

Note, it is a solution, as this is an Apple bug, but until Apple provides a fix, the mitigation tricks keep you running.
