Unity 2019.4.0f1 LTS WebGL 1.0 chrome nothing rendered

We've just updated our game from Unity 2018.4.12f1 and deployed it to players.
Some players got their Unity loaded but the only thing they see is our skybox. Log says that the game continues playing, there are totally no errors. We are not yet sure that the problem is only on chrome, but all reports by now were made from chrome players. We agree that these players have pretty old PC's but they were working fine on Unity2018.

I've attached DXDiag of one of our players and game console log. chrome v84.0.4147.135 (64). Please advise us something.

 

Okay, found the problem. Apparently newer Unity may put your gameObjects to some strange Z position on instantiation. Funny thing that it appeared on some rare specific devices, looks like it is connected to some CPU float maintaining. Just increase near/far of your Camera, or look for gameObjects that are Instantiated without position.
