Quick summary

The game simply refuses to boot through the cache building process, be it the HDD or disc version of the game, both ending in the same error (albeit with slightly different error message wording).

Details

(This is running on emulator version 0.0.2.1-13532-8316469c Alpha, latest at the time of writing)
I have seen footage of this game working on older versions of RPCS3 (circa 2020), before I started using the emulator myself, and it seems that SOMETHING must have broken between that and mid-2021, when I first tried to play this game.
Compatibility reports also LIST it as either in-game or playable, but said reports are also from 2020, before compatibility for the game seemingly broke.

Immediately after either generating or loading the shader cache data, the game will IMMEDIATELY hang on a black screen, with a cellGameGetParamString-type error message that was only recently updated to show more detail. This does not crash the entire emulator, but the actual game window itself has to be manually closed and cannot be stopped from RPCS3's menu.

Both versions are being run under all the recommended wiki settings (VBlank rate and the like are correctly set in their custom configuration).
The .rap file on the HDD version shouldn't be missing, as I loaded it into RPCS3 immediately after installing the game itself (and I have tried uninstalling and reinstalling both things multiple times, just to be sure).
Both OpenGL and Vulkan show the same results, so it's unlikely to be caused by either renderer.
My GPU drivers were a couple months behind at first, but updating them (and clearing the cache) did not fix the issue either.
Other games (including Tales of Xillia 1/2 which from what I've read used to have similar issues) have run perfectly on this same system.

The error, as stated, is present in both the DIGITAL [NPUB31133] and DISC [BLUS30903] versions of the same game.

EDIT: I should mention, I have seen one issue on this same github which also mentioned "deadlocking" on several games including this one, but it only referred to disc versions and NOT installed digital versions; that aside, I feel like the recently-updated error log data might shed a bit more light into things.

Please attach RPCS3's log.

(I would also provide screenshots, but as I've said the game simply hangs before it even boots properly so there isn't much to screenshot to begin with)
