FileNotFoundError when opening or saving files in network drives

Description

What steps will reproduce the problem?

I don’t know how to reproduce. I’d just opened a script and and clicked the Debug button Spyder’s toolbar. It took about 10 seconds to respond with this error.

Sorry for the slow follow-up.

At @dalthviz 's suggestion, I was able to able to reproduce the problem in Spyder v. 4.1.5:

1. Start that script (that resides on a network drive) in debug mode.
2. After hitting a breakpoint, disconnect from the network.
3. Upon clicking the Run Current Line button on the toolbar (to advance the debugger to the next line), Spyder displays the error message that the file could not be found and offers to either close the file or keep it open.
4. Clicking to keep the file open, Spyder shows the exception dialog with the traceback and the option to report the error.

Following those same steps using Spyder v. 4.2.1, I confirm that everything works as expected. Steps 1 - 3 seem to behave the same in both 4.1.5 and 4.2.1, but in Step 4 (clicking to keep the file open) quietly leaves the file open, with no further error dialog, so no offer to send the traceback along with details.

Thank you for the suggestions and for the great software!

Hi Daniel,

I reported the issue o Github just now, I was out of town for a bit, hence the delay.

Thank you guys for your help! Miklos

Oh I see @miklos-zoldi https://github.com/miklos-zoldi then could you open a new issue with all your setup details and traceback to check again this please? Thanks!
