Just saying. Sometimes changing the SDK version of the project may fix errors like this.

old thread, but google yadayada…

For me, the “Verify” option in the launcher fixed this.

EpicGames Luncher → UE → Library → EngineVersions → x.x.x → dropwown at “Launch” → Verify

Takes like 5min, and downloads missing files.  
In my case the file UnrealBuildTool.deps.json (and other files) was indeed missing, and it was successfully restored after the Verify.
