Hi. I can't open MATLAB after the update of my laptop.

The following keeps showing: "Fatal error on startup, failed to initialize java."

I just updated my java and clicked again but it didn't work. The above showed again.

Whenever I clicked on my MATLAB, in the file from User > AppData > Roaming > MathWorks > MATLAB, a new file "R2019b" will be generated.

I tried to rename it and delete it following advice from other pages, but none of them worked.

Please help me... I have homework to be done by this Wednesday. Thank you.
