FontSelf Custom Font not working Illustrator 2022

Hey everyone! So I made this font using FontSelf and then reloaded it back up into a new session and turned it into a live paint so I could paint bucket in the inside of it purple. Now, however, I get this error when trying to load it back into FontSelf to create a new '.otf'' file to load onto my website. I had another problem with fontself before where I had to Image Trace and ignore white and then expand and regroup my letters in my previous session with this font, so I am really just looking for a way to connect the paint bucket paint with the black and group them together somehow, huge headache and hickup in my website process HELP!!!
