Preview crashes: Cannot read properties of undefined (reading 'resource')

[jmvermeulen]

On VS Code 1.70.1 using the AsciiDoc extention the preview windows crashes. It stays empty and after +-15 sec VS Codes seems to crash. The file to preview is not relevant, its more or less empty.

Running on Kubuntu 22.04

It indicates that the webview couldn't be revived/restored because the state is undefined. Could you please try to close all tabs/windows, close VS code and try again?

[jmvermeulen]

I've opened and closed VS Code multiple times. All documents are closed. Including system reboots.

I cannot reproduce this issue:

[jmvermeulen]

Tried to uninstall VS Code, clear the /.config/code directory. Is there any cache or other folder I could remove for a "fresh" start?

[ggrossetie]

Not sure... maybe try the latest (beta) version 3.x?
