I had a big problem with it last week when creating a 20H2 installation USB, it created a FAT32 disk instead of a NTFS disk.
Unfortunately install.wim on that image is bigger than the FAT32 max file size. Meaning that while the USB booted in the system, the installation was not possible.
Of course the installer doesn’t keep the disk image it downloads to make the usb, so it’s another 5-6G download to try again - this may be problematic for people on limited bandwidth connections.
Personally I just created an NTFS partition on my USB drive and copied the contents of another windows iso over to it.
