Assertion failed: Assertion failed on expression: 'exception != SCRIPTING_NULL'

There are some errors that bothers me. Three errors that go one after another and repeats many times. It happends only when I open my project. It does not effect my game, build or any editor scripts at all, so it is not some urgent question. But i want to know what are those errors means and what i did wrong? (My project is pretty pig now, so i can't figure out what caused this).
Here is this three errors:

Code (csharp):

1. Assertion failed: Assertion failed on expression: 'exception != SCRIPTING_NULL'
2. Couldn't extract exception string from exception (another exception of class 'ArgumentException' was thrown while processing the stack trace)
3.  

(Yes, third is blank line)

Last time i opend the project this errors repeated 136 times, for a total of 408 error messages. There is no stack trace for this errors in console.
Unity 2017.3.1f1
