Used to play years ago and had similar problem but cant find how i fixed it (same computer).
PC client (not steam) - its a brand new install, it loads fine but after it has me log in and agree to terms, it loads this white screen with a loading circle - if i try to cancel out or back out, it opens up this windows saying i need to verify my age and 'proceed to verify', and just a loop of this until i close the game.
I think this is similar to an additional issue i had in past, where any in-game news or event screen would open up with this white window and loading circle. Not sure if its an issue with the in-game browser, or what is happening.
I can load into the game just fine on mobile, but that is not my desired platform - other games work fine on my PC: CZN, Arknights PC client, Endfield, HSR, ZZZ, NIKKE, etc etc
I have tried installing in through Steam client (same issue), reinstalling it, running repair, running as admin, updating graphic drivers, firewall and defender exceptions, setting high priority for graphics card, changing internet TCP/Pv4 settings, letting it sit with loading circle for hours, and other things that i have found online.
But nothing is working, and my GoogleFu is apparently also failing me.
Any known fix for this?
