Thanks for any help

Answer 1

This is because you have defined the open command, which is one of the main Python commands, as a variable.

At this point, it looks like you put this string in with and try to open a file using a string, which causes an error.

open = "C:\Program Files (x86)\BraveSoftware\Brave-Browser\Application\Brave.exe"

Rename the open variable you defined on line 146 to another name like open_ to fix your problem.
