Finally I was able to resolve the issue. I'm using 0patch on my business workstation and they inject their patch loader into every application (which works fine with everything so far, just nor GW2). After excluding the application from injection, the installer works fine again. I guess the game binary had the same issue. https://0patch.zendesk.com/hc/en-us/articles/4403637394706

I did not copy files from another machine. As the installer also crashes with the same issue (without any local files) it seems to be general issue. None other game or application has these issues on my system, everything is running fine.

I already tried that but it does not work in my case. The installer starts and crashes as soon as the self-update ist done. Same for 32B and 64B clients. So far this is the only application with these issues, nothing else is broken.

I can confirm this issue on Intel NUC8i7BEH with Windows 11 and latest updates. As I did not try GW2 immediately after the upgrade, I can not confirm if this is a GW2 or W11 problem. My gaming rig at home, also running W11, works fine. My NUC is using Intel graphics and I had DX-Beta enabled (was using dxproxy before). So far only this machine has the appcrash issue. All other games and software work perfectly fine.
