Opened Calibre and it's back to standard configuration: i had to retype the calibre library folder but also it forgot language and doesn't show plugins. What's strange is that if i open preferences->misc and open configuration folder it's still C:\Users\<user>\AppData\Roaming\calibre and the plugins are all still there.
Only thing i remember i did is making a new admin for win10 and demote the current to user
