This is just a warning that we are seeing an issue with the latest release when customers try to debug a project. Silicon Labs is able to reproduce the issue and we are working on getting a fix published as soon as possible. Until that fix is released it is recommended not to update Simplicity Studio at this time.
Silicon Labs will update this Knowledge base article as soon as the release has been published.
We apologize for this issue.
The fix for the debugger issue has been published. If you previously updated Simplicity Studio and you update it again you should see two updates available, one for "Debug Adapter Support for J-Link - 4.0.6" and one for "Debug Adapter Support for C8051 - 4.0.2".
After installing the updates and exiting the Package Manager (Updater), Simplicity Studio has to be restarted for the changes to take effect.
Please let us know if you are still seeing issues after installing these updates.
