mouse/cursor not working properly on macos 26

Roughly half of the time, the mouse does not 'left-click' properly; upon left-clicking properly, it will instead right-click. This occurs with both the trackpad and the mouse. Restarting the mouse or switching to another application and back using F3 sometimes solves this issue, but not always.

MacBook Pro 14″, macOS 15.3
