Macbook Pro 15" 2017 bluetooth reconnects when mouse is connected

I have a Macbook Pro 15" 2017 and it keeps dropping and restoring Bluetooth connection when a mouse is connected to it. It never happens when only the keyboard is connected happens every several minutes or so when only the mouse is connected and happens like every minute when the keyboard and the mouse are both connected.

When this reconnection occurs, both devices are reconnected, not only the mouse.

Actually, if the mouse IS connected, but not used, this doesn’t happen.

Here are the logs from Bluetooth Explorer (I don’t know what might be relevant and what not):

I have already tried this: https://discussions.apple.com/thread/251251648
Both file deletion and device removal. And of course, NVRAM PRAM reset. Don’t really know what else can I do. I can buy another mouse, but I’m afraid this can be not its fault.

Please help me to fix this. It is very annoying and just kills productivity.

Here’s the configuration of my MacBook:
