I've tried all amd64 ISO-CD installers available here: https://cdimage.debian.org/cdimage/daily-builds/daily/
The computer is: Lenovo X1 Carbon Gen 6 Intel(R) Core(TM) i7-8650U CPU @ 1.90GHz Intel Dual Band Wireless-AC 8265 (iwlwifi loads fine, during installation) Intel Ethernet Connection (4) I219-LM Samsung Electronics NVMe SSD Controller SM981/PM981/PM983 Everything is currently working fine with Debian bullseye, therefore, it shouldn't be an hardware problem.
