you guys need to learn to backup your saves, I always make backups before doing edits, theres always a chance you can screw up your game, normally you can just make a separate save, but in this case, you need to backup the files manually.
If you can see the exact value of your hearts, Id advise searching for that value using cosmos, (4 byte int) use a heart then filter to you find the actual values where the counter is stored, then change it back to a reasonable number. Of course if the upgrades you can get for the hearts is just the counter, what does it matter if you cant upgrade it anymore?
Your saves are store here: AppData\Local\Remnant\Saved\SaveGames
If you really cant do it yourself, upload and link me your save, I will see if I can fix it for you
