Wireless mouse freezes on iMac

My wireless mouse keeps freezing even though fully charges. I have to turn off and restart my iMac to rectify this. I have a 2017 Retina 5K iMac with a 27" screen running on Ventura 13.7.8.

Any ideas?

Thanks.

To fix a wireless mouse that keeps freezing on your 2017 iMac running macOS Ventura, you need to force-reset the macOS Bluetooth background process and clear hardware caches, as this is a known bug with Ventura's Bluetooth stack on Intel Macs.
