If Studio One crashes specifically and exclusively when you open any specific plugin (e.g. Piapro Studio) then your best bet is going to be contacting the support team of the specific plugin.
If you contact Piapro's support team but they are unable to resolve the issue then you may want to open a support ticket directly with PreSonus technical support by logging at my.presonus.com , click the "Support" button, then click "Create a ticket".
And don't worry. Nothing you've said is stupid. We all have to start somewhere.
