Hello @VishalAvg
Thanks for contacting us.
Please try the following suggestions:
- Check the project encoding settings as shown below. Make sure it's set to UTF-8 or inherited from the workspace.

2.Clean the project, then create a new IDE workspace and import the project to test.
3.Update the debugger firmware using the LinkServer utility.
4.If the issue still persists, please try testing with a simple SDK example project to isolate the problem.
Let me know if you need help with any of these steps!
