nothing works to recover my saves

[arqui_alpaka]

I am new to the community and English is not my strong point, my apologies if I do not explain myself well.
well it happens that I was playing calmly, I was doing some tests on the interiors of the new unlocked cabins and I had reverted to the VAB, everything was normal, but when I was in the VAB I realized that I had all the pieces unlocked, but I couldn't use Not one, not even the ones that I had unlocked, I couldn't do anything, just see the description of the pieces and not exit the VAB
Then I got an error and the game closed.
After that and opening the game I couldn't access my save (120 hours), I tried to do solutions that I saw on the forum, but it doesn't work, replace "quicksave.sfs / quicksave.loaddata" with "persistent.sfs/persistent. loadmeta" and so on with other copies that I had there, but no one will let me load the game, I don't understand the reason, I would like to have help
I have the "ksp.log" but I don't know how to transfer it to the forum
I don't know if anyone knows how to repair these files, but I don't know if these files can be passed through a link

KSP .log, .craft and .sfs files are just text files, so you can share them by e.g. posting them on pastebin, or any filehoster of your choosing. What happened is that most likely your persistent.sfs (your savestate for the save) corrupted in some way and can no longer be loaded correctly. I can not tell without seeing it whether it was damaged beyond repair or not.
