Technically the project could be opened in MZ, if you had that, but I am unsure if MZ works on an M1 mac at all either, and even if it did, depending on what you need to modify, the editor might change something in the project and it might not work right anyway.
Depending on what you need, most things in the editor can be changed manually by editing the files with a text editor. If you need to change the animation of a skill, for example, the skills.json file includes all of the skills in a csv value that you can change without using an editor, and as long as you save it as the right format, and don't mess up the formatting of the file, it should work.
