Good evening! I have a big problem, I’m at the end of the project 80%. I saved the project, I exited the program and turned off the computer while it was turning off, I wanted to unplug the monitor and I removed the PC unit when I turned it on a few hours later I opened unreal engine, and in the content my file with the whole umap project no longer appears, but in the folder on the pc it appears, what could I do to reopen it because it does not appear in the program, I don’t know what happened.Thank you for help
