Assuming that you have a valid MATLAB license linked to your MathWorks account, you can go to the MathWorks Downloads page select the release you want to install on the left side.

I can`t launch installed r2023b version, fix for problem is installing older versions.
But it`s unavailable for trial period users, right?

will take you directly to R2021a download.
If that fails, then:
  • possibly you do not have a license for R2021a or newer
  • possibly you are using an instituational license for an instituation that blocks direct download
The link will not permit you to download R2021a if you are using a Trial license.
