If you have adopted a physical MFA solution (Yubikey) and they are still compromising your account, the most logical security risk are the devices that you have used to authenticate. My suggestions from simple to more complex:
Log out of Twitter on all devices. When using Twitter, log in on only one device, use Twitter, and then log out of Twitter when done.
Install all available OS and Application updates on all of your devices (computers, mobiles, router, etc) and reboot them all (some threats only reside in memory). An easy way to reboot nearly all electronic devices in your home is to shut off power for a few minutes at your breaker box.
Only use Twitter via a “live” OS. Tails is a great option. Ubuntu is also good. Create a bootable USB and boot to that live OS, use Twitter, then power off device.
Factory wipe every device and reinstall a fresh OS.
