Build log does not include stacktrace (Backend is Mono)

I recently updated from 2019.3.1f1 to 2019.3.6f1 and I've noticed that the log for standalone builds don't include the stacktrace anymore. Instead of getting script name and line, I get

which is painfully unhelpful when an error comes up.
From the searching I've done, Unity doesn't support stacktrace when using IL2CPP backend, but I've checked that I am indeed using Mono.
If anyone has any suggestions on how I might go about fixing this, it would be greatly appreciated. Thanks!

 

Make sure that stack trace isn't set to None in Player Settings.

 

Yeah, I checked that too. It's set to ScriptOnly for all types (which, I think is the default)
