How to fix this GUIDE problem?

when I start GUIDE in command line ,it sometimes show this error message, What's wrong? How to fix it?

My system is Win10 64bit, Matlab version is R2018b

>> guide
Caught "std::exception" Exception message is:
foundation::storage::provider::Exception
Caught unexpected fl::except::IInternalException
>> guide
Caught unexpected fl::except::IInternalException

[Rik]

What does this return as output?

clc,which guide -all

[Yonglei GUI]

When I restart Matlab, it usually works normally

>> which guide -all

C:\Program Files\MATLAB\R2018b\toolbox\matlab\guide\guide.m

May be some problems with permissions and access (if you are not an admin user), because MATLAB installed on system disc. Moreover, the GUIDE is a legacy tool, try

appdesigner

it is included in base MATLAB and you do not need any additional purchasing for using it.
