    I contact Microsoft support , for my case KB4492767 fix known issue in AOS. By the way, Crash and hang analysis in LCS has already discontinued. Don't waste time with it..

    hope this help others who have similar issues.

    Hi ,

    it's only the client or Server? I don't think Trace Parser will help you in this case. 
    Instead,  try to use LCS Diagnostics Tool to get visibility, you may use LCS Crash and Hang Analysis Feature based on your scenario 
    refer: https://cloudblogs.microsoft.com/dynamics365/no-audience/2015/03/23/crash-and-hang-analysis-on-lcs/ for more informatiion

     if you are restoring the database, you need to clear AUC files on clients under path C:\Users\<UserId>\AppData\Local , i've faced similer issue after restoring databases in SandBox (UAT) environments. if you are getting this randomly it's probably due to user cache (AUC Files).

    Hope this will help.

    Thanks,

    Amith
