@swampwalker’s theory is as good as any. Here’s another: you’re record cleaning process has succeeded in loosening stuff on your records through fluids, brushing and you’ve vac dried them, but there’s still contaminants on the record. I’ve had this happen on various occasions-- the stylus gets fouled by a "cleaned" record that really isn’t fully clean.
Only solution is to hit it again, and maybe change up your method if you are finding this consistently. I’ve never used your machine, but it looks very much like a wand type (VPI)- if it has a slot in the vacuum wand, it should be positioned just so to maximize vacuum power and minimize sticking to the record. The velvet lips have to be kept scrupulously clean (you probably do that, but just for completeness) and of course, overvacuuming creates static. If my theory-- which I’m only throwing out as a possibility-- is the cause, you might also think about a pure water rinse (distilled is OK, there is better) with a different wand if you can do it, but my bet is, your cleaning is causing the problem if the stylus and platter mat(s) of both your turntable and cleaning machine are clean.
NB: Looked more closely at a picture of what I assume is your machine, there is no platter as such -more like a Nitty Gritty in holding the record, not fully the size of a 12" LP underneath, so that shouldn't be an issue.
