BlueScreen after update emmc from 17.0.0 to 18.0.0

[Bertilax]

I have 2 Nintendo Switch - one is softModed (unpatched) and one with hwfly (latest firmware). The update for emmc (stock fw) on the unpatched worked fine -> AutoRCM OFF -> Autoboot stock -> Update without troubles.
My second switch is running now emummc with version FW 18.0.0 in Atmosphere but if i want to update emmc (stock), every time i try to update FW 18.0.0 i get a BlueScreen after reboot. It's a SoftBrick, because restore to version FW 17.0.0 work's without problems. After sysnand is restored from backup to emmc, the hwfly Switch can boot into stock firmware with software FW 17.0.0.
Am I the only one with this problem with hardware moded switch or is there anyone else ?
Am I doing something wrong ?
Did Nintendo some "performance update" to FW 18.0.0 to soft-brick after update ?
Even EmmcHaccGen knows version FW 18.0.0 - updating and resetting the system with tegraExplorer and FW 18.0.0 created, ends in the same BlueScreen too
Last way to try would be to temporary disable hwfly (put NAND EMMC back to stock position) -> update to FW 18.0.0 and activate hwfly again...

I had to update the atmosphere/package3 and fusee to the latest atmosphere versions. Apparently even though we're trying to boot stock, it still requires atmosphere to bootstrap it. The more you know.
