Studio One will sometimes hang or freeze when Hardware Integration is loading up.
Below is a manual fix to this issue:
Go to Start >> Computer >> Type in %appdata% in the browser >> PreSonus >> Studio One
Locate the "Services.settings" file >>
Open it with Notepad >>
For the heading that says "<Attributes friendlyName="PreSonus Hardware Support" enabled="1"/>"
change the '1' to a '0'
so it should look like that exactly, with a 0.
Go to File >> Save. >> Then, close the file.
Restart Studio One and the problem should be fixed.
