Having now Internet back what was not the case when I blocked and had to reset my Mikrotik. I found this in the Wiki:
Configuration parts to watch out for in exported .rsc files
Things that should be removed from export files that were created with: "/export", before attempting import on new device.
Interface renaming that is in conflict with default ethernet naming scheme.
set [ find default-name=ether5 ] auto-negotiation=no name=ether1-gateway
set [ find default-name=ether6 ] name=ether2
set [ find default-name=ether7 ] name=ether3
set [ find default-name=ether8 ] name=ether4
set [ find default-name=ether1 ] name=ether5
set [ find default-name=ether2 ] name=ether6
set [ find default-name=ether3 ] name=ether7
set [ find default-name=ether4 ] name=ether8
In older version exports default entries might show with "add" instead of "set" command. That should be edited before import to avoid errors.
Check if interface/module: ether/wlan/modem/com/etc count match on new and old device. If there will some missing that will end up in error during .rsc import.
In case of problematic import attempt.
Reset the configuration on that device.
Run import command again with "verbose=yes" argument. It will stop also stop import process on problem which you already encountered, but will also show place where export failed. That way showing you place where things need to be edited in .rsc import file
So on the interface part I can only suggest to add an option to the export-file and that it is a system export and then the /interface part is committed. This also avoids 99.9999999% percent of the "verbose=yes" being needed.
Hey Mikrotik, think with us and solve the pitfalls before entering them in the Wiki. The Wiki is not accessible when the router does not want to accept the backup/import files.

I tried to use the run after reset and then the interfaces are also available probably so the import got stuck on the /interfaces with no entry in the log so you are banging your head on the keyboard why this likely option did not work.
