Registers Tree doesn't show device registers.

I am unable to inspect the device registers for my STM32U545 project. I can see the Cortex core Registers, and see them update as I step through the initialization.

The tooltip mentions an svd file, how can I check if it's set up correctly?

I have fixed things by switching from the snap version of VScode to the .deb version (which required temporarily changing the toolchain so that cmake could find ninja again).

Hi  @SamMiddleton 

could you please check in your STM32U5 dfp folder if you have any SVD folder with *.svd files in it 

could you add also please your extension version and your DFP pack version

Hi. I have the extension pack version 3.8.0. How do I find the other things you mentioned?
Three weeks ago, I was doing some testing with a nucleo board and could see the registers fine. I then worked on other stuff until the boards got made, and now I can't see the registers in my testing project either.

Well, I got the Snap through my distro's app center and the .deb from code.visualstudio.com, rather than from code.visualstudio.com/Download, but yes.
