Stuck at "finalizing the system update"

I went from the penultimate update of November to the latest one.

So it seems you missed this warning:

Week 08 2024: Development and Testing Updates

Update information specific to S7 /S7+ Users Build 1.17.1 will be rolled out to herolte and hero2lte tonight. 20 Feb This is for those who are still on Q download this build. This will also be on Q but it will have the necessary upgrade files. The actual upgrade to /e/OS R will happen once you get the v1.20 build. For the rest of the devices the release date of v1.20 will be announced later this week.

and you seem in a similar position to Problem update 1.20 on Samsung Galaxy S7

Late edit In case it helps others, there is this support topic, Upgrade the Samsung s7/s7+ to /e/OS R with SD card set as internal storage. Revealed with an image from e-1.17.1-q in this post Installation OS 1.20 sur Samsung S7 - #3 by Commando961
