Blog PRO M2 | Class Laminar not found

Good day,
yesterday we bought the Blog extension and tried to install it via upload, not composer. We have installed all amasty extensions via upload so far so we dont want to swtich our workflow since its easier for us internal to manage everythig we want to do.

Upon installing the blog extension and while running the `php bin/magneto setup:upgrade` and the `php bin/magento setup:static-content:deploy` afterwards we get an error displaying that the `Class Laminar/Uri/Http` wasnt found. We are now stuck at that point, when removing the files from `app/code/amasty/` and re-running the commands everything works as expected.

What do I need to do to install everything correctly via upload?
