BTT is preventing system sleep

Using BTT 4.170. macOS Ventura 13.4.1 (c). Mac Studio M2 Ultra with Bluetooth mouse, trackpad and keyboard (all Apple).

BTT is preventing sleep. If the Mac is inactive for the period set in Lock Screen settings the display turns off but the computer does not sleep.
Activity Monitor confirms BTT is preventing sleep.

Quit BTT and the Mac sleeps as expected.

Any and all help appreciated.

Thanks for reporting, this should be resolved in 4.171! (uploading now)

Thank you Andreas. All good with v4.171.
