Hi,
Welcome to the community and thanks for this report!
Can you confirm that none of your configuration for this project changed, either SonarCloud-side or on the project/build side?
Can you share your analysis logs?
The analysis / scanner log is what’s output from the analysis command. Hopefully, the log you provide - redacted as necessary - will include that command as well.
This guide will help you find them.
Thx,
Ann
