Tailwindcss intellisense doesn't work in tsx file.

I usuary use tailwind css with vscode. But one day, Tailwindcss intellisense doesn't work in tsx file. I configured some settings like below.

// It didn't work.
    "editor.quickSuggestions": {
        "strings": true
    },
    "tailwindCSS.emmetCompletions": true,
    "tailwindCSS.experimental.classRegex": [
        "className=\"([^`]*)" // className="From here
    ],
    "tailwindCSS.includeLanguages": {
        "javascript": "javascript",
        "html": "HTML"
    },

My solution was to delete tailwind.config.js and configure it again!!
