Error in chart editor

[ChiChrom]

Describe your bug here.

I'm not sure if it's here I should report about errors but here it is, when I open the chart editor for some reason it crashes and I don't know why, it was working well last time I used it and I do not recall changing smth after that unless it was deleting most regular fnf characters from the files

Windows

Did you edit anything in this build? If so, mention or summarize your changes.

I have removed most fnf characters except for bf, gf and pico from the files, removed all regular weeks and stages from the files, apart from removing I have simply added stuff for my mod

Missing health icon, based on what you changed you probably deleted dad's character file and/or assets which the chart editor uses as the default opponent icon (if you opened the chart editor from the master editor menu that is)

If not, then one of your characters used in your chart doesn't have an icon

I re-added dad's icon and it worked, thank you so much for the help!
