okay i found a solution here, this worked for me try it out
I have tried everything but nothing has worked. Then, i have started investigate "rgl_log_7092.txt" at "C:\ProgramData\Mount and Blade II Bannerlord\logs" . After the last line, there is no loading message and it ends. The file in the last line was "std_TaleWorlds_CampaignSystem-zho-CN.xml". I have just delete it which locates at "C:\SteamLibrary\steamapps\common\Mount & Blade II Bannerlord\Modules\SandBox\ModuleData\Languages\CN".
