Yeah my friend you have a total mess up here. But it make no sense that one GTA game is working and the other not. Before you do anything, just download a full data pack from a other www, I can not post links here, but its on googledrive also on mediafire and a spanish language site has it to. I think your p2p data file is corrupt.
Maybe this helps you better :
There are 2 'must do' different ways to install correct plugins. The one is to use Tools and the other one is to use tai conf.
The Tools install the plugins in different folders and tai plugins go into a specific folder.
I use real Vita card, so I have 'ux0:tai' open over molecularShell (or vitashell).
I have only kubridge.skprx and fd_fix.skprx into this folder, no other skprx file. You must open the config.txt file and write :
*KERNEL
ux0:tai/kubridge.skprx
ux0:tai/fd_fix.skprx
Close and save the file. Go back into the Vita settings, Henkaku and use reload taihen and reboot device. This is something that you can not do with autoplugin since you need a restart in taiconf for specific plugins.
storagemgr.skprx and libshacccg.suprx you install it over tools, NOT tai and dont copy the files into them.
And libshacccg.suprx is highly important for PC ports.
Use the Tool Adrenalin for all the PSP stuff.
delete these ones :
nonpdrm.skprx - this is for real VITA game backups, you dont need it for homebrews. I dont have it
repatch.skprx - YES delete, it conflict fd_fix ! you dont need it
itls.skprx - ? dont know what it is ? I dont have it
capunlocker.skprx - ? dont know what it is ? I dont have it
must have :
henkaku.skprx - Dont touch this one ! (main hack on your vita)
molecularShell - DONT LOSE IT highly important ! Tool
storagemgr.skprx - for sd2vita, yes (or somethiing else)
libshacccg.suprx - install over PIBconf Tool ! PC Ports need it.
kubridge.skprx - plugin over tai conf. PC and Android, Dreamcast emulator need it
fd_fix.skprx - plugin over tai conf.
(!) pspemucfw - install it over Adrenalin ! (dont use it in tai conf.) Extra PSP
Maidump and nonpdrm.skprx is both for VITA game backups, remove copyprotection or something like that, I dont have it.
You can find for all plugins a full info this site and how to use it correct :

You also find there updated versions of VPK files for all your ports and informations how to work with it.
Maybe GTA was updated in data files ! and you use a old one with a new VPK ?
