Ok, managed to solve it. After some (extensive) troubleshooting, here's what was causing my issues and how I fixed them.

My MB (ASRock B650M-HDV) is a budget board that struggles to maintain a stable PCIe Gen5 link with the RTX 5070 Ti, apparently. This was causing PCIe recovery errors (the link dropping and reconnecting repeatedly), which corrupted memory transfers between the GPU and the system. Checked this with HWInfo. Fixed it by forcing PCIe Gen4 in BIOS under Advanced → AMD PBS Option → PCIe x16 Link Speed → Gen4.

I was also using Resource Adjuster with its experimental options enabled, apparently that was causing aggressive VRAM allocation. Combined with the unstable PCIe link, this was triggering an access violation crash always at the same offset inside GTA5.exe (01410bfa), making it look like a driver or hardware issue; I'm not sure if this option works well for other people, but even with PCIe Gen4, it was causing crashes for me.

Also, not sure if that caused any issues, but I changed it just to make sure: battleye was active as a Windows service while the game was launched with -nobattleye. This caused BattlEye to detect the process as invalid and terminate it externally after some time, showing as exit code 0xcfffffff in the launcher log with no crash dump generated. Fixed after disabling BattlEye completely through the Rockstar Games Launcher settings instead of just using the launch flag.

Hopefully this can help someone in the future, although I'm not sure what exactly solved it or if some of those fixes were needed, but this is what I did. Thanks @Lennyy for the help too.

Just coming back to this to hopefully help someone, I ran some extensive tests and it seems that disabling HAGS on Windows solved my issue completely – it could be due to my GPU (RTX 5070Ti) being too "recent" for the game, since the Enhanced doesn't have that problem, but I don't fully know what caused it.
 
Turning it off on Windows 11: right click your desktop > display > scroll down to graphics > change default graphics settings and turn Hardware Accelerated GPU Scheduling off. Restart the PC and the problem is gone – tested for around 15 play sessions, each 1+ hrs long, and not faced the same issue again.
 
Keep in mind, this will disable the frame gen if you use that in other games, but for me it's completely worth it, since I don't personally use it.

Update: I've ended up redoing my mods folder. I was using the same one ever since the release of LSPDFR 0.4, so it was probably pretty broken anyways. Works great now.

Coming back just to update if anyone else has the same issue - VisualV and NVE are crashing games that are not updated to latest version (like mine). I did a backup before the update and am still using the old version. The solution is to download a old version of VisualV or NVE - I'm personally using VisualV V1.0.580 and it is working well.

Hey there! Have you tried setting the Plugin timeout threshold to 60000? I see right now it's set to only 10000. You just need to open RAGEPluginHook.exe with shift pressed and change it here. This should prevent the game from freezing and fix the crash.
 
Also, if you have ScriptHookVDotNet, try using the nightly version from their Github page. I had a lot of crashed when loading with the latest "stable" version and that fixed it. Hope it helps.

Yes, just add the field "extra_1="False" in CustomRegions.xml, DefaultRegions.xml and SpecialUnits.xml files - for example:

 
You just need to change whatever extra number you want to disable. The files are located at plugins\LSPDFR\UltimateBackup.

According to Razed, you can disable it by:
 
 

I would replace:
mods\update\update.rpf\common\data\ai\weapons.meta
mods\update\update.rpf\common\data\ai\weaponanimations.meta
mods\update\update.rpf\dlc_patch\mpbusiness\common\data\ai\weaponheavypistol.meta
mods\update\update.rpf\dlc_patch\mpbusiness\common\data\ai\weaponanimations.meta
 
with the backup outside the mods folder, that'll probably solve it. Just keep in mind you'll lose any changes you made manually or with other mods for those files.
