-have disabled all installed extensions -been downgrade subsequently to 1.58.2, 1.58.1, 1.57.1, 1.56.1 - and still get the same symptoms i think it's a system problem but i don't know what to inspect

mjbvz commented 3 years ago

Does this reproduce in the latest VS Code insiders build with all extensions disabled?

lexxwork commented 3 years ago

vscode 1.60.0-insider vscode 1.60.0-insider

mjbvz commented 3 years ago

Does this happen for every project you open? Can you share the project that causes this issue?

lexxwork commented 3 years ago

It happens only if I have .jsconfig.json in project with such content:

{
  "compilerOptions": {
    "module": "commonjs",
    "target": "es2020",
    "checkJs": false
  },
  "exclude": ["node_modules"]
}

lexxwork commented 3 years ago

I have figured out the problem I have added video files with .ts extension and this is subject. I have solved the problem excluding folders, thank you for support ) The issue can be closed.

Great find!
