POE2 Can't login to specific character

Same for my 92 warrior cant log back in after going to my hideout.

Peeps found the solution:

Simply go to Library on Steam, right click POE2, click "Manage", and then verify files. After the files are verified you can log in to your character.

Similar issue happened to me yesterday when I played with a trial of chaos. I was not able to play smoothly with my main character, but no issues with other characters. I forced the game to quit, then I can log in, but when changing maps, it blocked on the loading page often (not every time, but about 1/3). I had to force to quit again. I tried with a different PC, the issue persisted.

Finally, the issue resolved by changing the server from Canada East to California. It works fine so far. This is definitely a server-side issue. I will try to switch back to Canada East when the server is restarted.
