VSCode become laggy after some time and then crash (reason: crashed, code: 132)

[BungaaFACE]

Type: Bug

With verbose mode i see many

potential listener LEAK detected, having XXX listeners already

REFUSES to accept new listeners because it exceeded its threshold by far

SLOW task detected (744ms) but renderer profiling is disabled via 'application.experimental.rendererProfiling'" vscode

And then got crash with:
CodeWindow: renderer process gone (reason: crashed, code: 132)

Verbose log:
vscode_log.txt

I think this is because one of extensions, because on other profile no such problems

So I tested some things, here what i got:

• Lags starting only in html files
• After disabling Django extension lags stopped
• my settings for html:
  "files.associations": {
  "*.html": "django-html"
  },
  "emmet.includeLanguages": {
  "html": "html",
  "jinja-html": "html",
  "django-html": "html",
  },

I dont know if extensions are conflicting each other or there is a problem in this particular extension

Thanks for identifying that, can you file an issue against the extension too?

In case there is anything for us to look at, here's the stack that's producing the listener warnings:

I dont think this will work. last extension update was 5 years ago.
