I'd guess it's trying to start the correct MiniBrowser but with the system (i.e., wrong) WebKit?
Comment 2 Alexey Proskuryakov 2022-05-16 08:53:32 PDT 
Does the run-minibrowser script work?

No.

Would help to have a sysdiagnose to investigate. My bet is that we've broken Minibrowser launching when using the Open Source SDK somehow?

I think someone from Sony reported the same thing a few days ago.
