Windows 10: My mouse and rarely my keyboard keep disconnecting and reconnecting in fractions of a...

My mouse will disconnect for half a second and then reconnect randomly while I do anything on my computer. Sometimes my RMB and LMB work but my sensor cuts out for the short period of time. Every single time it disconnects the usb disconnect sound plays and I drop frames when I'm playing any game. It used to happen to my keyboard but I updated the drivers and that solved it. I have restarted all of my usb root hubs and tried connecting my mouse to every usb slot on my computer, and I've used my mouse on other computers without issues. Every single problem has started since I downloaded windows

The mouse reconnecting / disconnecting

Recently, the mouse I've been using has been being weird, I've learned to deal with it. By being weird I mean its been disconnecting and reconnecting whenever the dongle is in a certain direction. Yesterday however, the mouse started disconnecting when I
plug it in, and reconnecting when I unplug it, I've spent a good chunk of my day trying to figure it out and I just can't. Please help.

Mouse Model: Logitech
G403

Mouse sometimes disconnects immediately after launching Opera Browser!

My mouse disconnects and reconnects on rare occasions, something I believe is not a hardware issue or a loose USB connection, which I had initially thought.

I use Waterfox Classic Web Browser by default and mouse never disconnects. I kept a note of all the dates when the mouse disconnected.

18th of January: Immediately after launching Opera Web Browser

10th of February: Immediately after launching Opera Web Browser

05th of March: Immediately after launching Opera Web Browser

03th of April: Immediately after launching Opera Web Browser

It turns out that immediately after launching Opera Web Browser, on some rare occasions, like once a month the mouse will disconnect and then reconnect again within 1 second! I have no idea what the problem is, but at least I can rule out my Mars Gaming MM5 being faulty because it is happening only upon launching Opera.

With Waterfox this doesn't happen ever. The issue seems to be some conflict with Opera and my mouse only. Xbox One Controller and keyboard never disconnect. In the past this was not happening. It's an issue that started last 6 months approximately.

I tried looking at Youtube videos that suggested going to Power Management mode and unchecking the box where it says "Allow the computer to turn off this device to save power", none of these methods have worked at all so far.
