help [java] 1.20.1 world suddenly doesn't want to boot up anymore and can't even start on safe mode

single player world

to make it clear this error occurred without me changing any file or adding a mod, i've been playing for some time and then it randomly tells me the world got corrupted or some

anyways here's the things i did to (unsuccessfully) resolve it:

renaming the 'level.dat_old' to 'level.dat' file in order to load the backup; nothing

used MCA selector to at least copy the chunks in a new world with the same seed (taken with NBTexplorer) but the chunks near my base appear as unrendered and when i paste them into the new world nothing happens

my only 2 backups are also corrupted for some reason and the most recent one is almost years apart

the only thing that i think could be the issue is me using a duping glitch as it happened right afterwards but i've done the same duping strat dozens of times and always succeeded so honestly i'm just lost

this world means a lot to me please and thank you :)

[1.20.1] [java] chunks start rendering extremely slowly when going far out in the world

so basically after i fly for like 1000 blocks from base the chunks loading becomes hindered as well as ping lag even though im in singleplayer i've tried changing every setting but it wouldnt fix
