I can not open my official game project in version 4.19, Unreal Engine 4 is rubbish, all my work for nothing, I hope to see someone succeed creating a game like me, because I doubt it, 99.9% blueprints and style Grand Theft Auto 5, I want to see who beats me , I retire, if you want a commercial project do not do it in Unreal Engine 4, do not recommend it, then you can not open it and you screw all your work you’ve invested for years.
Did you attempt to automatically convert the sole master copy of a project between engine versions? There has never been a guarantee that this process is without issue. If you use source control, as everyone should, then it’s a simple revert and a loss of an hours work, not several years.
No, is that the versions I have are those that mention and I have not done very well in those less than 4.19, that I always succeed and I will try but doubt that fix it, what fails is the files to run the project in Unreal , I appreciate your input.
