GitHub Copilot seems broken (Cube IDE 1.19)

[NickO]

Running ST Cube IDE 1.19 on Windows 11, co-pilot autocompletions seem to be causing an issue. I see the suggestion, then a dialog pops up saying the following:

An internal error occurred during: "Generating completion...".

Invalid thread access

I look at the error log as I see the following:

Failed to parse wmic output

Hello @NickO 

I'm currently checking this behavior. I will be back to you asap.

I am using Windows 11 Version 10.0.26200 Build 26200

Hello @NickO 

Just to confirm, which version did you use exactly?

[NickO]

Just Copilot (I avoid nightly builds)

[NickO]

A new update to copilot has just come in. Completion seems to be working now.

However, I notice in the error log I still see this logged every second:

eclipse.buildId=Version 1.19.0

java.version=21.0.3

Ok, I've stopped the periodic error message by disabling com.st.stm32cube.ide.mpu.remote.serial

I did this by editing C:\ST\STM32CubeIDE_1.19.0\STM32CubeIDE\configuration\org.eclipse.equinox.simpleconfigurator\bundles.ingo and commenting out the lines that refer to this plugin (which I understand is not needed for MCU development).

All seems well now, but the AI suggests this:

"The root cause of the error in STM32CubeIDE on Windows 11 is the deprecation and removal of WMIC (Windows Management Instrumentation Command-line)."

Hello @NickO 

Let’s try reinstalling WMIC by following the steps provided in  LINK 

[NickO]

ok, I'll give that a try... I'll report back

[NickO]

That fixed it. Many thanks.

As WMIC is deprecated, presumably this can be addressed in a future update (which I hope there will be, not quite ready for the VS Code version quite yet!)?
