There are no issues with other levels. I am only using a level that cannot be opened, and I am using the latest version of the engine and cannot open it with a new version. How can I solve this problem
Hey there @user_ce4665483c7673b30ecb536402668cd9fd2b0354e46da33784c117! Welcome to the community! Is this a level you made in that project? What version of the engine are you working in? Are you using source control of any sort? Are you working alone or in a team?
Assets have a built in hard lock on versions as they could cause catastrophic issues otherwise. This error is usually specific to the out of version problem, but if it’s cropped up another way that might be a serious issue.
