cant import my librarys! help!

i tried to import a library to my librarys panel, and i got an error message "the library you're trying to import did'nt work. The file might be corrupted." but im sure it isnt.

so then i tried as a workaround to load them using windows>swatch libraries>other library, dragging and dropping into my swatches panel and choosing the "add selected Swatches and Color Groups to my current library."  but my library panel froze and only worked when i restarted illustrator.

is there a way to import my library directly into the library panel, or is there a workaround that will do it?

Please help!!😔

Thanks!
