Lemme explain a few things that might already be enabled. If you enabled google backups or samsung cloud backups, texts, call logs, settings and a few other small things are backed up.
You can't just hard copy things over, would be easy if you could.
Since you get a few minutes before it crashes. Load it normally, settings, click your name at the top (above connections), press samsung cloud, scroll down and press backup. Hopefully everything is enabled and has a recent date. If that's the case, everything listed is backed up. It's not all your data but it's some important things.
If backups are off or really out of date, you might have enough time to run a backup before your phone crashes. That should backup your texts. (Saying as you mentioned them specifically)
For contacts, hopefully you've been saying them to either your google or samsung account. But to be sure, settings, google, all services, google contacts sync. Make sure it's on, also enable sync device contacts. Google should now store your contacts.
The google backup takes a long time so not even worth mentioning here.
Apps won't have data backed up but they should reinstall after a reset. Just as if they were brand new.
If whatsapp is something you use, it also has a backup system. Depending on your wifi and how many messages you have, you might be able to run a backup before things crash. If you already had backups on within WhatsApp, then problem already sorted.
For the reset thing, you should have options to only reset certain things. Since your phone is running an older one ui version it might not have these options
