DISCLAIMER_1:Lychee slicer users: It is a known issue for us, in version 5 they messed up obj import somehow. We've already contacted them about this, but did not get any answer yet. Until they solve it, here are some workaround:1, try to use older versions (version 4 works perfectly for us)2, use chitubox, there is no error in IT3, open it in an editor software (meshmixer, 3d builder, etc) and save an stl.
