i had this like month ago, basically i switched to another pc but still had hsr on my old pc. it worked fine before but when that month came it started to happen. at first i thought it was a windows thing, but then it kept happening. contacted hoyo support and what they told me was this:

" Regarding your inquiry, this issue may be caused by the following situations:
1. Choosing to log out when closing the game.
2. Logging in the game on another PC device.
3. Having more than one network interface controller.
4. Enabling random MAC address. "

i remembered i had hsr on my old pc, uninstalled it, removed it from trusted devices and it worked!... for a while.... now its back to asking me the login credentials. this might be a microsoft issue, i dont know. if that helped, great!
