Persistance state file not generated

[Shimoon]

After the recent persistance update, I deleted the required item but when I try to set a colorscheme I get the folowing message : "Themery error: Could not open file for writing: C:\Users\<user_name>\AppData\Local\nvim-data/themery/state.json".

I tried to reinstall Themery for it to auto generate the state.json file but it doesn't seems to work either. Do I need to create it by hand? If so, what should I put in it in order to make it work ?
