Button color bug

Please refer to the attached image.

I manually entered the color value and pressed the enter key to change the value in the sidebar. But the background color of the Button has not been changed.

Additionally, in the root directory, execute the command 'npx tsc' to generate a package in the esnext format, which differs from the format of packages downloaded from NPM. NPM downloads packages in the CommonJS format, and also includes a package in the index.mjs format. Could it be that my command syntax is incorrect?
