Issue Preventing Restart: A Non-Functioning Entity Thwarting Operations

Hello. I would appreciate any insights on how to determine the identity of the unknown item labeled as “t”.

Even after interrupting the restart sequence and checking the task manager, I did not come across any entry associated with the letter “t”.

Could you suggest alternative methods that I could explore to uncover the identity of this mystery item labeled as “t”?

This issue has persisted for around 2 months, ever since I switched from Windows 10 to Windows 11.

Thank you.
