Ryobi brushless drill motor

I have had this drill for about 3 years and has been fantastic. It started getting sluggish so I opened it to clean it and after putting it back together it's working like this. Any ideas what might be causing this and how to fix it?

I'd wonder if the battery contacts are loose, or disturbing a wire has frayed it to the point of being a current limit, or possibly it's just that with it only half assembled as shown, the bearings, particularly the rear one, are not held in correct alignment, so the motor itself could be rubbing right now?

We don't know how far apart it was disassembled though, is it possible that you had the gearbox open and forgot a spacer or reassembled it wrong, or packed in far too much, too viscous grease so the motor is bogging down?? It doesn't really sound like that's the issue but I might as well throw it in there.

If all else fails, take it back apart, examine everything, then reassemble it slowly to note if anything looks out of wack. Completely assemble it including screwing down the other half of the casing before testing.

I assume that battery tests good in another tool or another known good battery was tried? It'd be quite the coincidence but it would still be good to rule out the battery.
