KOreader drops me back to Kindle Home

Hi all! My first time trying the LanguageBreak on the Kindle 2022.

1. Kindle Basic 2022 (is that KT5?)
2. firmware updated from 5.15.0 to 5.16.2.1.1
3. Completed LanguageBreak
4. Installed:
5. kual-mrinstaller-1.7.N-r19303.tar.xz
6. KUAL-5b5d1d2-20231104.tar.xz
7. koreader-kindlepw2-v2023.10

I can get into KUAL and select KOReader. I can then see it say "Starting KOReader" at the bottom and then it blanks the screen for a second and drops me down to Kindle Home again.

I have tried doing a clean install with the zip as well as erasing the koreader and extension/koreader directories with a reinstall of the txz contents, but get the same results.

Is there a known problem with KOReader, LanguageBreak, and the Kindle 2022 on 5.16.2.1.1?

How should I remedy? Just reset the Kindle and start jailbreak and software installs over again?
