Selenium basic issue

hi i dont know how to use selenium basic with secure workbook.

my case :
selenium basic installed pc , no comp. file with secure book

selenium basic browser (crome and brave) crash after open. macro not respond.

how can i fix that ?

Is selenium an external process to Excel or invoked through VBA code?

both. its some kind of lib which open browser and automate it. because of this its only works or invoke with vba.
