Please attach the dmesg output for your system. Other than the error, is the GPU otherwise working correctly?
The GPU otherwise is working correctly. On other Operating Systems.
Also this issue is exclusive to attempting to boot the live systems or installations from a mounted version of the respective downloaded ISO file.
If you flash it to USB, the installation works fine, despite somewhat the same errors. I am writing this currently from a working PopOS installation.
