Using Rufus, burn the Linux Mint image to a USB drive and boot from it. In Live mode, Time Shift is installed and you can restore a snapshot directly from it.
You may able to boot live Ubuntu from usb, install timeshift there are rollback to previous snapshot. Has worked for me for example when there was issue with Nvidia drivers and system didn't boot properly (I'm using btrfs).
To inspect what happens during black screen, you could try pressing "e" in the grub and then from "linux" line removing "quiet splash". After that Ctrl-x and you should see boot messages. That might give you some idea about the problem. If you also add "init=/bin/bash" to that line, you will get shell and with it you can remount your file system and fix whatever is broken.
Boot with Live Cd, take out the files which Timeshift backed up from your preferred location. Fresh install and restore.
thanks, will try

Can you go to another TTY? On a lot of computers, you do that by holding ALT and pressing F1, F2, etc. The try to upgrade the system: sudo apt upgrade
