Your test project on an Intel Mac mini produced this output when run from Terminal when a save was attempted (which failed):

$ ./testjpg
DCT coefficient out of range
WARNING: TButton.Destroy with LCLRefCount>0. Hint: Maybe the component is processing an event?

Curiously, when compiled on an M1 Mac mini (aarch64) it works as expected. All relevant version details are in my signature.
