with disable all extensions

/duplicate #136874 and maybe fixed in upcoming 1.65. Can you test with Insiders?

@gjsjohnmurray

Thanks for you reply! Insiders still display error about [Extension Host] .

[aGensinger]

and in /duplicate #136874, some operations is confusing for me.

[aGensinger]

@gjsjohnmurray @vscode-triage-bot Maybe it's because of my software environment，could u help me to analyze it?

[gjsjohnmurray]

pinging @chrmarti

[chrmarti]

@bpasero Is there a simpler way than changing code to enable tracing for deprecations (#136874 (comment)) in the extension host?

[bpasero]

Not to my knowledge, maybe @deepak1556 knows.

@aGensinger This appears to be from an older version. Could you retry with the latest VS Code Insiders version?
