Describe the bug

After updating to 6.0.1 the QR-Code on Labels are not working for newly created assets.
Old assets for which we allready generated the Labels are working fine.

Error Call to undefined function Com\Tecnick\Barcode\imagecreate()

It looks like it wants to access the QR-Code via IP, which of course wont work because of SSL Error. Maybe that has something to do with the error?

https://10.65.113.238/hardware/874/qr_code for example.

APP_URL is set to the public domain.

Reproduction steps

1. Create new Asset
2. Click "Generate Label'
3. Label loads but with broken QR-Code
   ...

Expected behavior

QR-Code on Label is visible.

I forgot to install php8.0-gd after upgrading PHP. It's working fine now.
Thanks :)
