SmartGit not working on RPi400: cannot execute binary file

Good day

I am trying to install smartgit on a RPi400 fresh install.

What I have tried:

1. I navigate to the directory that contains the smartgit.sh and run ./smartgit.sh Terminal returns:

>>If you experience strange GUI bugs or crashes, try setting GTK_THEME=Adwaita.
./smartgit.sh: line 150: /home/.../Programs/smartgit/jre/bin/java: cannot execute binary file: Exec format error

2. I have also tried installing Java (java install link)
3. I have also uncommented GTK_THEME=Adwaita within the smartgit.sh file.

Any help would be appreciated. Thank you

I contacted SmartGit and was told that SmartGit is not supported on on Raspberry Os at all. :(
