Hi, I'm hoping you can help. I've been using Mass Search/Replace without issue, but today, after working fine for a while, I tried to run it through an action chain and I got an error: TypeError:Invalide Column metadata. Now whenever I try to run anything, or even customise the plugin, I always get this error.

I hadn't changed any columns since my last successful run, so all I can think of is that Action Chains has somehow broken it. I have tried restarting Calibre and restarting my PC. This is what I get from the details of the error:
