Answer 1

Usually we have two sides methods to deal with deleted environment variables issue.
1, recover environment variables from a same system computer
2, restore/reinstall system
Windows 10 has built-in reset channel, type reset this PC in search box and click Get started, this way will keep your files and reinstall current system.
Or you need to find another healthy computer which using the same version of Windows 10, copy its environment variables then paste on your PC.
