installation Intervention Image php 7.3.5

perhaps compare with a working composer.json and check your error composer.json file is there any syntax or case sensitive typo error near "database/seeds"...

i'm sorry but i can't understand what i can do

What i meant is the error seem happened at the composer.json file it tell that some error on the "database/seeds"

[RuntimeException] Could not scan for classes inside "database/seeds" which does not appear to be a file nor a folder

and one of the reasons causing it may because of some typo errors on the composer.json file

anyway, it's better to tell the folk what had you did and at which point it hit error with some screenshots or copy the entire error message instead of in words, guesssing work is tired and may lead wrong direction...

styling your code or message nicely to easy others to read and understand (https://help.github.com/en/articles/basic-writing-and-formatting-syntax)
