Second error looks like you’re opening a project with incompatible dll files that need to be recompiled, or the file is missing.
Maybe try to delete the engine and version and re-download or try a different version.

If you updated the engine in the middle of the project, try going back to the previous version. Many problems may occur if you do that.

Yeah sounds like there is a problem with the project.
