swagger ui freezing in expanding POST or PUT method

we added swagger to our project that developed with Web Api core, the problem is freezing swagger ui  in expanding PUT/POST methods (when use complex objects . GET methods works correctly) . we don NOT  use Dto models and all APIs work with Domain Models directly. 

 I think its because of many relationships  or  recursive relationship between models.but its impossible for us to change application structure .  

Is there any solution to solve this issue without big changes in project
