Endless loading when trying to load any household (specific save)

So I haven't played sims since 22.8.25 and ill try to list what happened yesterday when i wanted to play again NOTE I've never used mods or CC ever:
-bought the new royal game and the business hobby expansions
-installed them
-Started game Saw that previous played game was a very old one (from 2017)
-Repaired the game
-saves did not appear
-went into save folder, i saw that saves from 2025 was there
-thought it had to do with one drive (the game for some reason is located on user-onedrive-documents and not c:-user-documents) no idea why but ok
-I turned off onedrive last year so i think it was onedrive messing it up.
-I uninstalled the sims 4
-removed the onedrive electronic arts file from one drive documents to another place (hoping it wouldn't reinstall into same onedrive folder
-after reinstall the folder was back on one drive -.- (i hate one drive)
- pasted back the saves but was still not showing in game
-I googled and seems my 2025 saves had a strange naming. it had added a extra word, ex: "Slot_00000002-word.save" etc
-i red on some guides that this is not supported naming.
-i removed the "word" and now the saves are back in game (yey)

NOW i can enter the saves and my old world, i can go into buildmode on my old plots, i have my families in the gallery, BUT i cannot play any of them, i cannot even create a new sim and place on empty plot and play them, the only thing happening is infinite loading.. what to do?

I ofc tried wiping all save and starting new game and it works.
thank you for all help <3
