My file is gone, I don't think I will play this game ever again (a rant and a cry for help)

My save file got deleted today, I had it since 2019 I don't know what to do, especially after seeing all the posts about this and no solution in sight

It was my first ever no man's sky save, I had billions of units, ships I found and restored with friends back on xbox, I traveled all the way to the 10th galaxy, dozens of bases, hundreds and hundred of hours and it's all gone.

I don't think I will ever get back on the game if I can't get this file back, I don't have the time and energy to spend to farm all these S ships and all the stuff I had.

If anyone can help here's what happened : I play on PC (xbox launcher, no mod no vr) but the file was originally created on Xbox, I switched on PC years ago and never had any issues until today.

A couple days ago, a pop up saying "impossible to sync with the cloud" (something along those lines, my game is not in english so it isn't the exact words) showed up everytime I launched the game, with the options "try again" and "play offline", i chose the latter because I couldn't get my game to sync.

No problem for the last few days but today when I started it, the game was able to sync with the cloud but my main save (the one transfered from xbox) was gone, all the other files (created on pc) are still here.

No luck trying to log back in the cross save website ( https://cloud.nomanssky.com/ )

I can't find any of the save files on my PC and I can't even get an old version of the file through the cloud, I don't mind losing a couple days of progress, but 6 years is a bit much

I would be eternally grateful and build a shrine in game to whoever finds a solution
