I feel like I had this happen on my PC (midline/potato, to be honest) - IIRC, what worked for me was when you are at the loading screen, do NOT click in the circle to load the game when it is ready. Instead, go to the Settings icon in the bottom right corner.
No confirmed fix yet. Players suggest: Last night when I first got this error, I tried to go to Window Security and do a on off.
No confirmed fix yet. Players suggest: A new gacha could adopt your suggestion as a gimmick to draw players in, but it's not likely a pre-existing one would change.
Suggested fix (unconfirmed): Turn off Windows Smart App Control or add an exclusion for `HorizonWalker.exe` in your Windows security settings.
No confirmed fix yet. Players suggest: Jupiter EX stigma set to go with it.
