Unity Shader Variant Error on Build

Hello everyone, I am having trouble with a strange error.
I am using the Unity Engine about four years but I didn't see this kind of error.

When I want to build the game with custom shader from Asset Store (Flat Kit), or Stylized Grass shader;
Unity fails the build then gives me error:

"FlatKit/Stylized Surface has too many Shader variants(9437184).."

It says "remove this Shader from the Always Included Shaders list" but if I do this builded game shows me pink no shader textures.

This is the error:



This Is Game View In Editor:






Unity Version: 2020.3.8f1 Personal DX11

My Specs:
Intel core i7-10750h 2.60 GHz,
16 GB Ram,
Nvidia 1650ti 4GB

I'm gonna miss the deadline if can't fix it. Anyone can help me?

 

Edit: This is the scene after the build without adding shader variants on "Graphics Settings"

 

Ask asset developers for support involving their assets. We can't tell you what the potential shader variant issues here are.

 

Thank you for your answer, but I want to know is there any possible way to dont get the " Too many variants" error on build. Because I must use them.

 

Why "must" you use every shader variant?

 

Oh, I am sorry for my bad language. English is not my first langue.
I was saying " if I was remove the shaders from (ALL SHADERS INCLUDING URP MATERIALS), graphics settings include list. Game building with pink error textures. If I add the shaders on the list, Unity crashes without errors or gives me the error that I posted for this topic.
I searched about this error but I did not found no one had this error before. This is very different error to me.

As I say, I developed a couple finished games with this engine, but I didnt get this type of error until this time.

BTW thanks for supporting, I am open for any different solutions

 

See if this helps.

Thank you, I tried it, but my shader got millions of variants so I cant add one by one to a preloaded shader list. I will give another try btw. But this did not solved the problem yesterday.

I hope it helps this time...

 

This did not help. Game built with pink no material shaders again...
