Framework7 generate-assets doesn't working

This is what I get when I am running the framework7 generate-assets command in the CLI:


I have waited for 15 mins or so.
I have tried to delete the F7 CLI manager and reinstall it, but it didn’t help.
I made sure that the files are have the same names, same sizes and PNG formatted (not transparent).

the framework7 generate-assets --ui pops a blank page:

Looks like you have created your project with older version of Framework7 CLI. Create new project in other directory with same settings, and copy package.json from new project to the current one

This is complicated I have Git in the project… I have reinstalled the Framework7 CLI but it doesn’t help.
