VSCode Extension (Simulator) broken in latest version of VSCode on MacOS

Unpaired8373

After updating my VSCode installation the Simulator does not start anymore. All I am seeing in the debug console is

Uncaught Error: Please initialize WebviewPanel before using it: "WebviewPanel.init()" main.js:1031
getInstance	@	main.js:1031
(anonymous)	@	main.js:996
dispatch	@	main.js:1

@Unpaired8373 Does this happen with a fresh application from Create App or only with the one you’re working on? Our team member with an M2 Macbook reported not being able to reproduce this error.
