TypeScript build tasks fail (likely new in version 1.64.0)

[klylesatepic]

Issue Type: Bug

Attempt to run a build task (Ctrl+Shift+B) for a TypeScript project. Both "tsc: build - tsconfig.json" and "tsc: watch - tsconfig.json" show the issue for me.

I see the following output:
> Executing task: 'c:\path\to\project\node_modules.bin\tsc.cmd' -p 'c:\path\to\project\tsconfig.json' --watch <

ParserError: 
Line |
   1 |  … path\to\project\node_modules\.bin\tsc.cmd' -p 'c:\Epi …
     |                                               ~~
     | Unexpected token '-p' in expression or statement.

The terminal process "C:\Program Files\PowerShell\7\pwsh.exe -Command 'c:\path\to\project\node_modules\.bin\tsc.cmd' -p 'c:\path\to\project\tsconfig.json' --watch" terminated with exit code: 1.

Terminal will be reused by tasks, press any key to close it.

I played around a little bit, and I suspect that adding a & before the tsc.cmd path would fix things. I don't have a good way to confirm that, though.

I am reasonably certain that nothing about the project changed to cause this to break -- it was working before I updated to VS Code 1.64.0 and not working after.

Looks like a potential duplicate of #142196.Do you agree @alexr00?

My use case works again as of version 1.64.2. Thanks for the quick fix!
