@UltimateModuleCreator ... should PHP version lock to 7.4?
If I do:

1. git checkout .
2. change symfony.lock version number to 7.3
3. delete the vendor folder
4. composer install

then it will work without any issue

"php": {
     "version": "7.4"
},

@srenon This app should work for any php version starting from 7.2.5. You can change your version in symfony.lock. I will try to find a solution today so you don't have to change anything. Or at least include some extra steps in the install process.

@srenon I added symfony.lock to .gitignore this looks like it solves the problem. Can you confirm?
