I hope I will not sound too blunt 
This is an unusual and special case where an unusual for /e/OS required Pre Upgrade measure was not applied.
I do not have the phone, so no direct experience, just reading posts from other users who faced this. Full reading of my earlier links will be a good idea.
This question was asked as it was significant to the required Pre Upgrade measure, and the answer will help me to speculate less about the current issue.
Regarding the PIN issues I said
This was to avoid speculating but I can visualise that no PIN can be validated due to the current state of the data partition and probably its encryption; this would be linked to any absence of any earlier installed SD card used as Portable storage (unknown to me).
Your images are of Download mode show that FRP is off (good) 
Download mode is a solid part of Samsung and is protecting the phone (good)
Just checking … Recovery mode is reached from
With the device powered off - hold Volume Up + Home + Power. When the blue text appears, release the buttons – but you say
You can use Download mode to reinstall Recovery using the install page instructions https://doc.e.foundation/devices/herolte/install.
Some users have said this looks a bit intimidating, I think as the methods for Linux and Windows seem mixed, but actually the logic is correct.
There is also the method in this link for Windows: [HOWTO] Install /e/ on a Samsung smartphone with Windows easily. Written when TWRP was the regular Recovery the instructions apply equally for e-Recovery. If you were going to attempt to sideload back to e-1.17.1-q- you would probably choose recovery-e-1.17.1-q-20240208379201-stable-herolte.img
