What's Wrong?

Since yesterday, I have been unable to compile and run my automated test cases using Claude Code on my Asus ZenBook. I have already tried the following troubleshooting steps as suggested by Claude:
Reinstalled Claude Code with the latest ARM64 version.

Reinstalled Node.js with the latest ARM64 version.

Additionally, I attempted installing both Claude Code and Node.js in the x86 versions—as suggested by Claude—even though I was certain they would not be compatible due to the architecture mismatch between my ARM64 CPU and the x86 installation packages.

Sincere and Humble request to please look into this matter and help me out from this situation.
Now the situation is that even if I do not type any query it is throwing the error code straight away.
