USB export problem

Hello everyone! I hope you are all doing well.

I would like to ask if this has happened to any of you:

Every time I export my library to my USB, some songs are not read correctly, or the waveform view disappears, it asks to reanalyze.

All of this happens randomly in different songs and taking into account that my entire collection is correctly analized and I don't have any problems in rekordbox, this only happens when exporting and when playing it is a big problem.
