How to fix bad file descriptor error in VS Code? "File changes watcher stopped unexpectedly. "

[Hevin]

I have vsc version 1.66. I'm getting the following notification:

File changes watcher stopped unexpectedly. A reload of the window may enable the watcher again unless the workspace cannot be watched for file changes.

Hi,

We have had reports of this issue earlier this week as well, but no solution yet. I have forwarded your logs to the developers, and I will let you know when I have an update from them.

Best regards,

Marte

Hi,

The developers are unable to reproduce the popup message, only the console messages. They believe it might be a bug or an environment issue that this manifest in a popup warning. However, it does not seem like this issue should interfere with the current functionality. The developers will try to eliminate the non-functional watchers that are created for the not-cloned repositories, but until this is released you can just ignore the message.

Best regards.

Marte
