So I am using Identity 2.3.0 1.18.2 Fabric,
(identity-2.3.0-1.18.2-fabric.jar)
but the game crashes instantly when I boot it up, is there something I am missing here for key information?
Like any possible mod conflicts or something else or is it the mod it self that's causing issues..?

Minor Part of the crash report:

Update: So I went through my mods list and put one mod after another back in one at an time, and I might have the answer already to this crash report, from my discovery, First Person Model Mod by tr9zw has been causing the issue as after I had place it back in and then removed it but then put back the mods from before, basically all the mods I had but minus First Person it booted up just fine, so I basically just solved my own issue report! Well then 😅... I'll close this issue ticket but will update via new one if any other issues pop up.
