Many thanks Ronald aka Ron aka @ronnz98 - and best regards to your building machine AMD Ryzen 16.
The update had to be done via PC and adb sideload, as e-Rcovery v1.16 does not offer an option to sideload via USB stick.

Images extracted by me for a clean install:

Update via e-Recovery V1.16: Install completed with status 0.
Android security update: October 6, 2023
microG services: Version 0.3.0.233515
Notes:
e-Recovery has also been updated to version 1.17 (20231112) as requested.
Glyph interface - settings for glyph lights only work after restart. This is the same for LineageOS 20.0 and LineageOS-20.0-for-microG.
At first glance, everything works as it should - including fingerprint.
If you want to try it out - there is also an unofficial TWRP-Recocery (not yet tested by me. Use at your own risk!) twrp-3.7.0-A12.1-spacewar-Nothing1-boot_2023-07-20.img
