registerFromPath() works but register() does not with the same file

[ghost]

Hey, I'm using @napi-rs/canvas (^0.1.53) under Bunjs (1.1.17) and Windows 11.
When I load a font with the registerFromPath() method, everything works normally. But when I load a buffer of some kind or a buffer of this same file, the text no longer appears on my canvas. How do I get .register() to work?

Work:

GlobalFonts.registerFromPath(process.cwd() + "/assets/fonts/Poppins-Bold.ttf", "Poppins Bold"); // return true

// ...

ctx.font = "36px Poppins Bold";
ctx.fillText("1x8S7bjie...", x, y);

Result:

Don't work:

const buffer = readFileSync(process.cwd() + "/assets/fonts/Poppins-Bold.ttf");
// or
const buffer = Buffer.from("<myBase64FontFile>", "base64");

GlobalFonts.register(buffer, "Poppins Bold"); // return true

// ...

ctx.font = "36px Poppins Bold";
ctx.fillText("1x8S7bjie...", x, y);

Result:
