The EV3 software opens the first project with no problems, but when I open a second project it crashes and terminates. I tried to install the EV3 software on Windows 10 (MS Surface laptop i7,16GB RAM), or on Windows 7 (Thinkpad i5, 16GB RAM), but problems remain the same.

Please guide me on how to fix it. Thank you very much.

    You can look in the error log file located at: "<User Profile>AppData\Local\LEGO\MINDSTORMS EV3\crashreports". Maybe there are some useful information in it. But most likely, as MindS1 said, you need to re-create the project. Commented Aug 31, 2018 at 6:44

If the same project crashes your software on multiple installations, the problem is the project file itself. Sometimes files get corrupted. Unfortunately the only real solution is to recreate your project.
