Jonathan White 6481ecccd7 Fix crash on screen lock or computer sleep 
* Fixes #10455
* Fixes #10432
* Fixes #10415

Prevent setting critical key components to nullptr when database data is cleared. This can result in a crash due to race condition between threads.

Added a bunch of asserts to detect this problem and if guards to prevent actual crashes.
