If you have Time Machine disk, use it to revert to a time before you upgraded to Mojave.

Restore your Mac from a backup - Apple Support

Follow the directions for: Restore both MacOS and your files.

If you do not have TM then you need to erase the disk and install High Sierra. Do a complete backup before this as your data will be erased.

Get macOS High Sierra.
