What's the problem? Describe what went wrong.
This game has some in-engine cutscenes that naturally transition to gameplay. When these transitions happens, the game drops right down to 0 FPS during a few seconds until it resumes normally.
What steps will reproduce the problem?
Play the game, the prologue shows this off inmediately.
Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
Is the issue present in the latest stable version?
No idea. I'd try it, but 5.0 throws a lot of errors at me because it can't read my SYSCONF.
What are your PC specifications? (CPU, GPU, Operating System, more)
i7 6700k 4.2 GHz
16 GB DDR4 RAM
Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
The problem happens at 0:35, 1:03, 1:58, 2:22 and 2:44
This happens on Direct3D11, Vulkan and OpenGL. On Software I'm not sure, I think it happens too but it's so slow in the first place that I can't tell.
I will provide anything else that you ask for

This is that the logs say after having one of these freezes (and after closing the game)
This is the first time I use the log feature, maybe I did something wrong?
And yes, the game stops for a moment in console. I'm unable to test in on real hardware right now but if you check any gameplay in youtube in the real console, it's there. However, it's much less pronounced, lasts much less, and the audio doesn't stop or get messed up. It's just a really quick stop. Here you can see it (right after the letterboxing dissapears):

It's not a bug unfortunately, but it is an issue.
Basically if a game overflows the far code cache, we have to flush it which causes a stutter.
This seems similar but not identical to my issue: https://bugs.dolphin-emu.org/issues/10014
From what I remember, there were also slowdowns during gameplay after the initial slowdown from the cutscene transition.
