Well if you can SSH into your Kindle you can (as a temporary solution until you downgrade & fix KUAL) just directly execute the scripts & commands that KUAL extension's button "action" would normally do.

As for the downgrade: you could either do necessary edits to
that /etc/version.txt manually via SSH / USBNetworking as mention in original discussion of that latest downgrade method:

or download and copy "Downgrader 2.0" KUAL extension:

And execute the appropriate script command (that you would find and copy from extension's "menu.json", you would need to either use absolute path instead of the relative one written inside "action" property or cd into extension directory) via SSH to automate that file edit and triggering device reboot and firmware downgrade.

I"ve noticed that your profile's device info states that you have "Kindle Paperwhite 10th gen" and you original post you're asking about "Kindle 10th gen". So, which model is this discussion about?

Read both those threads very carefully especially the last couple in Downgrader 2.0 thread and seriously consider possibility of clearing all the necessary database files via SSH before doing a downgrade from 5.15.1.
And double-check that those 2 ota binary files are indeed restored otherwise that older firmware install will fail.
