It sounds like you're looking for a solution to a missing Bluetooth toggle in Windows 11, not an academic paper. However, if you need a related to Bluetooth issues in modern OSes (e.g., driver failures, UI inconsistencies, or radio management), here’s a suggestion:

"An Empirical Study of Bluetooth Connectivity Failures in Windows 10 and 11: Drivers, Power Management, and User Interface Gaps" (Note: This is a hypothetical but plausible paper topic.)

It would explore why Bluetooth toggles disappear due to driver crashes, BIOS settings, or Windows servicing stack issues — combining user behavior analysis with OS telemetry.
