How do I exit form "Failed validating schema (@jupyterlab/apputils-extension:package)" in Jupyter lab?

Question

I am trying to access jupyter lab using ssh. I am fallen in this error message shown in the image that I attach:

It is a similar problem reported in this StackOverflow post.

My problem now is: how do I exit from this and obtain my command line again ? As you can see I have tried q exit() quit() q exit ...

Thanks in advance.

Try Ctrl+D. Is perhaps the cause of the error a bad PATH variable? Which are the operating systems on both sides? — harrymc, Feb 04 '23 at 18:40
@harrymc thanks for your comment. I tried Ctrl+D but it stays still there. My computer is Windows 10 and on the other side, to be honest, I do not know... either Linux or Windows. — HelpNeederStudent, Feb 05 '23 at 10:04
The best solution might be to fix the error, which might be because of a mixup of versions. Otherwise, if the program is hung, killing it might be the answer. — harrymc, Feb 05 '23 at 10:29
Try Ctrl-C, but your options are limited if you don't control the server. Get in touch perhaps with the server's administrator for solving the error itself. — harrymc, Feb 05 '23 at 10:40
@harrymc Ctrl-C has worked thanks! If you post it as an answer I can give you the 50 bounty points. — HelpNeederStudent, Feb 05 '23 at 16:44

The solution for this problem was to use Ctrl+C to end the hung process.

This is a strong-arm solution that aborts the interactive program, but it's effective in most cases.
