Steps to Reproduce

1. Create a new folder on the file explorer.

3. Choose the newly created folder.
4. Add a tsconfig.json file.
5. Right click the tsconfig.json > Build.
6. See error on output Tsc.

Start at the context-menu Build path for tsconfig.json and inspect how it resolves the TypeScript compiler; compare that lookup with the missing tsc.exe path shown in the output. Reproduce the listed steps, and consider it done when Build launches the available compiler and completes the tsconfig.json build without the missing-file error.
