combine error "two to geometric condition"

[Prothean]

Hello everyone, I can't use the "combine" command to join two complex geometry bodies within the same part. the error that gives me is "two to geometric condition". I'm going to see the interface between the two bodies but I can't figure out where the error could have created me. Does anyone know how I could solve this problem? use solidworks 2019

thanks in advance

without files, without images is practically impossible. you should imagine something complex that is not even described.
attach the file

I tried to attach, but the file is too big

use forum tools to attach files.
supported formats are those of the image of this post https://www.cad3d.it/forum1/threads/foglio-personalizzato.57105/#post-445975

I can't tie in any way, the file is too big! are 25mb of sldprt that does not reduce much even zipping

don't join them because there are a lot of areas that intersect or have no perfectly combing faces.

Yeah, I figured... Is there a way to figure out what the faces don't match?

check one for one and correct the model.

for those who want to try the union of the two bodies here is the allegianced file.
the weight was reduced by transforming the part with bodies externally referred to in part with bodies without references, moreover I added the function eliminates bodies that allows to further reduce weight
