(win10,R2019a)Error Starting Desktop <java.lang​​.NullPoin​t​erExcept​io​n>?!

I have installed and activated the R2019a Matlab on windows 10 successfully, but I got the error below on startup----just as the picture shows.

I have googled this type of error and someone told me it happened because" the user account folder name under C:\Users " is Chinese instead of English.

And it's not recommoned to change the name in case that it would mess up my profile.

So I wander if there is any solution possibly to solve this problem and I would be much more greatful if you can answer my question.
