Hi everyone i would like to report, this same bug just happen to me today after the update. I even reinstalled the game and also deleted my gw2 cache. Then i thought because i updated my graphics driver the night before it might be that. But when I tried my alt accounts to log in the gem store works fine no issues, when i use main account that is 8 years old now and open the BLTC it crashes every time. The error report log for the crash under ERRORS reports ..
