Likely related to #265 but I don't know enough about this stuff to tell if it is (so apologies if this is essentially a duplicate).
No, this is unrelated.
Can you upload a copy of your configuration file? Your loot_table_blacklist contains either an empty value or an invalid value: you need to specify a loot table in the format of minecraft:chests/desert_pyramid for example.
The actual issue here is that it's trying to parse the string looking for a ":", but isn't finding one.
Unfortunately, the configuration system for Fabric is nowhere near as flexible as Forge's (not that Forge's doesn't have its own issues), and thus there's no validation for values.
I've pushed a new version which will still error when the configuration is invalid, but it will inform you of which configuration entry is a problem and, if there is a specific entry that's causing it, exactly what that entry is.
This will be included in the next Fabric release, which I'm about to make.
