Error using uiopen (line 175)

I am using MATLAB Online R2019a. I tried to open a script and it is showing an error Dialog as you can see in the attached image. Similar error is also there when I tried to open some other scripts. I would really appreciate if anyone can help me solving this issue.

Two requests.

1. The error is happening on line 175 of some function or script and that line is likely calling uiopen(). Could you show us that line of code?
2. Could you should us the output of the line below?

which uiopen -all

D: file names are never used by MATLAB Online, which runs on Linux.

@Salma Taj

Please show the code in which you invoke uiopen?

It might be necessary to use the debugger,

dbstop if caught error

and see what happens. For example there could be a problem if you have your own open.m somewhere on your MATLAB path.
