[BUG] Issue with tweaks.

[ty817]

Prefixer v1.4.1-Turing
Ubuntu 24.04
Installed via uv.
So my issue is whenever I try tweaks it prints:
Malformed tweak! Too many fields! Should contain ('path', 'args')
Prefixer v1.3-Turing changed the syntax for the regedit task. Read the wiki

Ok, so I went to wiki and trying editing json myself. But whatever I do, it either spits lots of python error or just results in same output. For example this jsoin80 for dotnet8 looks sane to me and doesnt work:
