RE: VS Code freezes on pristine builds

Confirm there is a bug with the Windows 11 notification toast. Not sure if it is with VS Code or nRF extension. Though I have not noticed it using VS code with other compilers. When I disable it as my post above suggests I have not seen the issues again. You can close ticket. Thank you.

Some additional info. Given it was happening right at the end I have since disabled the OS notifications (so called "toast notifications") in both VS Code and in Win11 itself. In VS Code search for toast in settings and turn it all off. Win11 it is under Settings > System > Notifications. Fingers crossed I have done around 10 pristine builds now and not seen it again! Will report again if fully resolved after little more time.

Similar but not the same I dont think. That ticket talks about it stopping on the "Found GnuLd:" step. I always get past this step. My issues always shows as the build fully complete but VS code just not releasing control back. The window UI thread does not freeze - you can still switch windows back and forward to it. However, it does not accept further input, and its taskbar icon appears like this, with or without the red tint depending on if it is the active window.

As above though it happens at random and from any kickoff of a deeper level build - pristine request, edit pjr file or edit board definition files (custom board). It never does it from just code file edits. NOTE it is a dual core nRF5340 build using sysbuild with application and ipc_radio in the build list.
