rekordbox 6.6.5 audio playback lagging

When I imported my most recent tracks to rekordbox, I noticed that the beat grid appeared to be off almost exactly 1/2 beat during playback on my laptop. I proceeded to correct the beat grids and export the music to an SD card as well as a thumb drive. When I plug these devices into CDJ2000s, the beat grids that I fixed are off by 1/2 beat. So I went back to rekordbox and had the tracks analyzed again by the software. Again, the grids appeared off, but I plugged the drives into my CDJs anyway. The beat grids were then perfect. That ultimately means that there is a lag in playback on my laptop which is a new Asus with Windows 11. Any educated guesses as to the problem?
