modifying project yml aggressively drops project from solution context

[vescovd1]

Type: Bug Report

Describe the bug

• OS and Version: Windows 10
• VS Code Version: 1.87.2
• Extension Version: ARM CMSIS solution v1.33.0, Keil Solution Pack 1.18.1
• Target Device: STM32xx
• Other extensions you installed (and if the issue persists after disabling them):
• A clear and concise description of what the bug is. Solution with multiple projects, modify (editing) one projects yml (for example simply just adding a new file to the build list) drops the project from the active solutions context. This is extremely annoying as it seems every time I make even minor changes to the project yml the project is dropped from the solution context and if I try to trigger a build it builds some other project in the solution instead of the project I modified the yml for. The only solution I have found is shut down VSC and restart, then the modified project reappears in the solution's context but is unselected.

To Reproduce Steps to reproduce the behavior: See above.

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Additional context

It appears the yml syntax scanner is too aggressive and drops projects from solution's context and does not allow simple yml edits.

Thanks for reporting this issue, it is very annoying. We'll get a fix out for it as soon as possible.

Version 1.33.1 released today has an initial fix for this. The projects will not be dropped from the context if the YAML is invalid.
