Linux Mint With Full Disk Encryption Wont Boot?

I know it's not new. I've been reading tons of forums these days....try this and that. I know very little on how work Linux Mint in the depth.
so I'm looking for help on the similar problem that was posted before.
I backup the disk 2 weeks ago so it's not that critical...if there's no simple way to recover the system as it was. I'll install Mint 19.3...still I'd like to see my stuff as it was.
Thank you
