"search files by name" can't find .env(dotenv) files in vs code

Definitely, there are .env files in workspace VS code. But can't find .env files using "search files by name" (the palette when press cmd+p or ctrl+p)

I tried,

1. restart VS code several times.
2. update VS code to version 1.71.1
3. empty workspace settings file .vscode>settings.json

files in workspace

no matching results
