Hi I'm running into the same issue described here:
https://itch.freezing.top/t/4428696/solved-sprite-doc-error
The problem is, there doesn't seem to be a way to trigger the permissions dialogue when I run CF Advanced Exports from the file menu. It just pops up the "attempt to call a nil value (global 'Sprite')" error.
I'm guessing something funky is going on with my script/extension permissions for Advance Export, due to having installed an older version of Advanced Exports in the past, but I can't figure out how to fix it so that the permissions dialogue appears. The usual tricks like Uninstalling and reinstalling Advanced Exports, or restarting aseprite, do nothing.
Any tips on how to get permissions sorted out?
