There has been an oversight with the newest release where a couple of plugin files were overlooked and didn't make it into the software.
I have attached the HotKeyDrawSize.zsc file and InteractiveLight.zsc file to this response. You will want to copy them into the ZData/ZPlugs64 folder of your ZBrush installation.
By default that folder is located at C: > Program Files > Maxon ZBrush 2025 > ZData > ZPlugs64.
