Before GPL, when using Steam to precompile shaders for Apex, some of the shaders were insanely big. As in after everything else has finished and the counter is at 99%, 2 threads are left to compile for like 15 minutes
That might be related.
Sounds like there's some slow shader compiles happening in the background that we end up waiting for. All compiler threads have an early-exit path and in something like God of War, exiting the game during shader compilation works just fine here.
I recorded a log where I went to the connection screen, then immediately after exited the game and let the game churn on whatever it did

I'm having this same issue, and in my case most notably for Apex Legends. Not sure if it's tied to shader compilation or not, but this happens very frequently, and I think is a recent matter (weeks?).

If I exit out of a game normally while GPL is compiling a massive shader cache, the game will stay open. The game will still stay open even if I Alt+F4 as shown in the video. @ishitatsuyuki has confirmed that this also happens with Overwatch
