'Analysis failed. There is not enough memory available' message

I use a pioneer DDJ-400 and connect it to rekordbox on my hp Chromebook which is operating with windows 10. I use the version of rekordbox that comes with the controller and I download my songs to my computer in wav format and then import them onto rekordbox. Recently, I keep getting this message pop up when I load a track onto a deck and I haven't been able to practice with any new songs. I don't have that many songs imported onto rekordbox (I checked and I have about 42) so I don't understand why this is happening/how to make it stop? I tried to look online but can't find any mention of others having this issue. Is it an issue with my computer or the version of rekordbox that I'm using? I doubt it's to do with my computer as I already have these songs downloaded and saved onto my laptop, rekordbox just doesn't analyse them. Please help as I'm still learning to DJ and I struggle to stay consistent, and this is really holding me back :(
