Swap Library error

Hi, I duplicated 2 files, a library and a design file. The new design file is obviously still attached to the previous library. I want to attach it to the new library. Everything is still exactly the same. I open the library panel in the new design file, add the new library to the file and detach the old one, then I click on “swap library” in order to replace components and styles in the file, but I get this error ID: ba6fb6fe90044b46a5917a85bf89e636. Did this happen to anyone else? If yes anyone found a solution? How am I supposed to swap my libraries if this doesn’t work, I tried more than 20 times over the week end.
