I created my project on 4.19, then decided to switch to 4.21. I worked on the project for many weeks, decided to build it, but I get this error. I do not know what to do, help, please.
Unreal engine 4 log: link.
Thank you in advance for your help!
I found a solution to my problem!
I just moved the folder “content” to a new clean project.
It works for me!
I tried to moved the content to another new-stablished project ,and I opened the map that’s supposed to have a full equipment of all components ,however it losts some parts when migrated to a New project .Do you know what 's the problem ? THX
