I was removing the mod from the mods folder. I was downloading the mod from Curse.
Maybe it is related to other mods which making things with the shulker boxes?
They would be:

• ShulkerBoxTooltips
• EasyShulkerBoxes

You need to give modid.mixins.json a unique name (simpleshulkerpreview.mixins.json preferably). If another mod provides this file with the same name as is the case here they'll clash. modid.mixins.json is the name used in the Fabric example mod, so it's likely another mod forgot to change it as well.

Thanks @Fuzss, I thought I'd adjusted that but must have missed it! Appreciate the help.

@mrniddala I've pushed a new release that you can download in my GitHub releases, and I'll be uploading to CurseForge shortly too. I'll close this ticket now, but feel free to make another if the issue pops up again for some reason!

It works without any problems and looks super fancy, yay!

Fantastic - enjoy!
