PS4 How do I debug ps2 emu freeze?

[SWEET_TOOTH]

Hello, I have a frustrating problem and can't find the cause of it. The idea of this post is to find out how do you debug ps2 emu on ps4 when it freezes? And how do i find a fix for it? My example:
I have convert my ROM from PS2 iso to PS4 pkg using PS2-FPKG_v0.7-Beta
ROM: SLUS21807
My configs are:

TXT:

--vu1-di-bits=1

--vu1-jr-cache-policy=newprog
--vu1-jalr-cache-policy=newprog
--vu1-mpg-cycles=2000
--vu1-opt-vf00=2
--vu1-opt-flags=2

--vif1-instant-xfer=0
--ee-cycle-scalar=2.0

--gs-kernel-cl=h2lpool
--gs-kernel-cl-up="h2lpool2x2"

LUA:

-- Jak v2

local gpr = require("ee-gpr-alias")

apiRequest(0.1)

local eeObj = getEEObject()
local emuObj = getEmuObject()

local patcher = function()

end

emuObj.AddVsyncHook(patcher)

Every 2nd-4th race it freezes on the loading screen. How do I detect the problem and move forward?
I tried changing vu1-mpg-cycles and ee-cycle-scalar many many times and I get mixed results even when I found the perfect almost never stuttering config: it still freezes on the loading screen even if I load the same or different maps

I would gladly post this in ps2 - ps4 research but my account needs to be verified
