Description
any time i try to export or open a cmp file it gives me this error message. All it told me to do is report it too github.
This doesnt happen on my laptop only my desktop. Im running Linux on both. Both the plugin and block-bench version are the same on the 2 machines.
Error while exporting:
TypeError: Cannot read properties of undefined (reading 'i')
