No, the Insta360 Ace Pro 2 is not compatible with the Kingston Canvas React Plus V90 128GB.
Insta360 Ace Pro 2 has a microSD-only card slot. Its own product page confirms only microSD card compatibility -- a full-size SD card is physically larger than a microSD card and does not fit this slot (the reverse of the more common microSD-via-adapter case: here there is no adapter that shrinks a full-size card down to fit).
