Hi there! Can you take a look at this link and try all of the solutions? Let me know if none of them worked. https://royals.ms/forum/threads/having-trouble-with-the-game-client-come-on-in.142484/
This post right here has the same error you are showing, https://royals.ms/forum/threads/error-code-2147287038.123788/ The same “solution” to solve this one, was listed in that link I posted earlier Re download your client for the new patch update!
Then I’m not sure. All of the other posts with the same error code you are getting all got fixed by redownloding
