while exporting, doesn't work, pleases help, dont want to lose chats

pls help, it decided to put me those notifs when i restarted my pc one day, my data is still present as shown in this screenshot

even after screenshot 2, it still downloads a backup but it doesn't work when trying to import it in an incognito tab i don't want to delete my data because i don't want to lose my characters. sorry if this isn't usual, i'm new to this forum and perchance in general
