Help/Support [BACKPACK BRAWL] Game is stuck on loading screen

[Dark Light 8]

Hello,

I've recently downloaded a modded IPA from this thread : 

I followed the instructions, installed with Sideloadly and everything went smoothly. I verified the App, activated developer mode and the game launched correctly.
But after that, it got stuck in the loading screen indefinitely. This is what I see.
I tried to deactivate Game Center, created a new, fresh account through the OG game before retrying, but to no avail. 
At this point, I don't know what to do.

I'd appreciate any help.

I just tested and game load fine for me, on iPad Pro M2 18.6 using apple developer certificate + gbox to sign

Only issue is cannot retrieve save file from cloud

Damn, so that means the problem is definitely on my end, but I still don't understand the reasons.

I'm using an iPhone 13 - version 18.6.1, and I'm also using the App AdGuard. Do you think it could have an influence..?
