The item “MATLAB_R2022a” can’t be moved to the Trash because it’s open.

I am trying to remove MATLAB from my MAC, as the macOSX for 2022a installer failed to finish but somehow created the icon on aplications. I want to delete it it and try installing it again. But when I go to aplications and try to move it to trash it says "The item “MATLAB_R2022a” can’t be moved to the Trash because it’s open."

I can delete the installer file but downloading and opening another installer won't open the installation process.

Please help, what should I do?

Did you restart the computer already?

"installer failed to finish" - did you get any message?
