Hi everyone! I have this problem where everytime I upload a book through Calibre, my device works fine at first but after a minute it freezes, and I have to restart it to fix it. I tried uploading them the basic way (through drag and drop directly from my computer storage) and this problem doesnt happen. Has anyone else had this problem? Or any idea of how can I fix it? I tried searching through past posts but couldnt find anyone with the same problem, I would really appreciate the help!

For context, I have a Kobo Clara BW, and use Calibre with the Kobo Utilities and Kobo Metadata plugins.
