Describe the issue

Simply launching the 2021-10-16 build specifically breaks a fresh FHDB installation.
I had to image the HDD to reinstall.

Then I made a prepared multi-install memory card that I would use to boot from and restore for regular testing, opening the older 2019 version of LaunchELF, formatting the entire HDD, then launching FHDB Installer from mass to restore and boot just from that device later.

Deleting the FHDB CNF file or copying and pasting an old one to the same location would not help.
I changed other various FHDB settings like default browser mode and the OSDSYS options using the configuration, launching other programs, powering off and on completely frequently between each action, and none of those would cause the issue.

LaunchELF PS2 partition defaults:

  __mbr               128Mb       (Reserved for system)
  __net               128Mb
  __system            256Mb
  __sysconf           512Mb
  __common            1024Mb

I would add homebrew to the HDD under __common in a new folder and run from there. Some place I heard running homebrew from a mass storage device directly may be problematic, but I think has worked fine for me before, and also from the memory card, although I don't want to alter any data on those anymore, especially the one with the FMCB multi-install.

I just copied 2GiB of data from the beginning of my SATA Toshiba 80GiB HDD that I am using inside my older fat model PS2 with the HDD-Network adapter that should cover all of the relevant partitions, although I suspect an issue with the first, most important one, both before and after using the issue-causing wLF build. When running cmp -l, I see these changes:

      3073   0 260
      3074   0 113
      3075   0 371
      3076   0  15

When I take the first 1MiB from the 'before' data file and reapply that to the HDD, FHDB boots successfully again.
