LabVIEW: (Hex 0x417) LabVIEW failed to send variable to the script server

[HARBOUR]

Hi, I am using MATLAB script and it shows a following error when I run my LabVIEW script node. 

I have tried the solutions in this link,

https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019Lk2SAE&l=en-GB

The first one is doesn't work for me.

For the second one, the command prompt can not find the specified path.

For the third one, the LabVIEW and MATLAB are both installed in this PC, however I have no operating permission to get into Advanced system settings in my university computer.

For the last one, setting complex is also not working for me.

My LabVIEW2020 and MATLAB R2020a are running good when I use them separately.

Any other solution for this problem?

Ps: This is what my MATLAB command window shows:
