It may be worth suggesting trying different USB creation tools.
I have no issues with installs using the last couple of images, other than in qemu virutal machines, via virt-manager. Calamares crashes when opening there. Using them on my computers, I have had no issues, so far.
I use Ventoy, usually, which boots multiple ISO images directly - no ‘flashing’ involved.
Otherwise, I use dd on the command line. Someone notes that they were successful using Rufus on Windows using ‘dd’ mode. Various flashing tools can do things a bit differently from each other, and historically in my experience trying different ones can be useful when there are problems using in ISO.
