Hello friends!!

Lately, I've taken to multi-booting a whole bunch of different operating systems on my Thinkpad x250 with my new 1TB SSD for educational purposes. And, I find it very humorous to have such a varied collection of OS's and I enjoy finding ways to get them to play nice with each other. So far I've multibooted Solaris 11, Windows 10, OpenBSD 6.9, Arch Linux, Ubuntu Studio 21.04, Rocky Linux 8.3, Haiku R1/Beta2, in that order, and I've saved the last partition for Genode. I'm using rEFInd as my boot loader.

Here is my gdisk output for my SSD:
GPT fdisk (gdisk) version 1.0.6

Partition table scan:
 MBR: protective
 BSD: not present
 APM: not present
 GPT: present

Found valid GPT with protective MBR; using GPT.

When I attempt to format the final partition from within Sculpt 21.03b, I get a strange error:

I really want Genode to take part in this wonderful collection I've built. I wonder why it won't format?
