I reinstalled a prior version of VS Code and now I can once again open .Ipynb files no problem. I went from VS Code 1.49 down to 1.46.

I reinstalled a prior version of VS Code and now I can once again open .Ipynb files no problem. I went from VS Code 1.49 down to 1.46.

Didn't work for me. I'm receiving this message now:

Any other alternatives?

[HenriqueAJNB]

There is a similar issue here. It's seems a bug of version 1.49...

Hi all, thanks for bringing this to our attention and sorry for the trouble. I can repro this and it appears to be associated with the 1.49 upgrade. We'll look into this.
