MacBook Pro M1 External Display Issues After macOS Sequoia 15 Update

I would like to bring an important issue to the attention of Apple developers and engineers. After updating to macOS Sequoia 15, my MacBook Pro M1, as well as some other users' devices, no longer detects my external display. I am using an Apple Thunderbolt display connected via a Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter. This setup worked perfectly fine with macOS Sonoma and continues to function properly with older Macs. I would appreciate any insights into why this issue might be occurring and any guidance on how to resolve it. Thank you.

MacBook Pro 16″, macOS 15.1
