ULX cursor not moving/lag during game

ULX 1600dpi - 4k polling

noticing that while playing valorant multiple times that my mouse will stop moving completely and if I move just using my KB that the game starts lagging to the point where I start getting "low framerate" error messages from the game clearly stuttering etc.

it isn't until maybe after 15-30sec of just randomly tabbing in/out of the game trying to move my character around and just moving my mouse around that it just seems to unlock itself.

i have this same exact issue with my other PC as well and another mouse but the same model etc.

I've tried to disconnect/reconnect the dongle, remove the USB from the PC etc, turn on/off the mouse etc. nothing has worked so far for both pc's and both mice.

edit** I've had this mouse since the 2nd batch I believe and between then and now I've had no issues. This issue specifically happened to both pcs as of yesterday.
