MCUXpresso Installer is at v26.03. I first noticed this after upgrading and running the install. I see v26.06 is now current, I will install that and see what's what.
* I installed v26.06.117 and upon launching it, I just see the spinning icons. I will

I relaunched Installer via /Applications/MCUXpressoInstaller.app/Contents/MacOS/MCUXpressoInstallerCLI
to get more info. Launching from MCUXpressoInstallerCLI from my default environment I see this spinning behavior. When I relaunched from the GUI (OS X) a subsequent time the installer shows component status (installed, update available) with the exception of PEMicro.
-In the Debug Probes window, click Clean-up Debug and then click the Refresh button.
In the VSCode DEBUG PROBES window there is nothing to click. The message which popped up indicated that there is no 'provider' for the window. This message shows up in all the windows when first launched then goes away as MCUXpresso finishes loading (with the exception of the DEBUG PROBES windows). I guess I could blow away the MCUXpresso for VSCode extension and reinstall.
MCUXpressoInstallerCLI output once had this, might be hint for PEMicro:
