I can’t restore my SSD!

I can’t restore my internal SSD the format is APFS ENCRYPTED.

Everything begins when I try to download Xcode beta the size of Xcode is like 15gb the problem was that I only have like 10gb of space in my MacBook Pro and I have issues with the GPU and keeps restarting.

when I try to download Xcode knowing that I have less space in the SSD the computer crash and restart in that moment the MacBook stuck in the progress bar.

I try to recovery mode + internet mode + terminal + installing another Mac OS image to restore the SSD + nothing works to erase the disk or recover it.

everything seems that the drive is full and if you know the blocks in the SSD keeps crashing when are full!

Any clues of this issue or anyone knows another method to restore the internal SSD?

PD: now I am trying to boot with an external hard drive and when I login the file vault tells me to put the user and password of the disk and keeps thinking for hours!
