mpdf class not fount error CI 4.1.5

II found the error:

On my local lo server, I found that a php library was missing for gd. And this was causing mpdf version 6.1.3 to be installed, the current version is 8.0.10, however composer was not installing it.

So I installed the missing library, updated composer and everything worked perfectly, now I can use the mpdf library.
