No, the Insta360 X5 is not compatible with the Nextorage NX-A2PRO 160GB CFexpress Type A.
Insta360 X5 has a microSD-only card slot (no CFexpress support of any type). Its own product page confirms only microSD card compatibility -- CFexpress Type A uses a physically different, much larger connector and cannot be inserted into a microSD slot.
