OperaGX is no longer deleting the temporary profile in PortableApps\OperaGXPortable\App\OperaGX folder.
The presence of this undeleted Profile folder causes my OperaGX browser not load at startup until I manually delete it each time I need to use the browser.
The problem started with the last update.
A fresh install does not fix the problem.
