Symfony version(s) affected: 5.1.3

Description
I am reading the following YAML file, but I get a parser exception.

How to reproduce

This is the code:

        $config = Yaml::parseFile($ps_filepath, Yaml::PARSE_CONSTANT);

I am reading the following YAML file:

macro_scalar : /usr/local/fish
macro_list : [flounder, lobster, haddock]
macro_assoc : { 
  fish : [flounder, cod, haddock],
  shellfish : [scallop, crab, clam],
  other : [chicken, pig, cow]
}

override_value: "global"

This is the error:

Unexpected characters near "

override_value: "global"" at line 10.

If I move line override_value: "global" to the begining of the file, the problem dissapears:

override_value: "global"
macro_scalar : /usr/local/fish
macro_list : [flounder, lobster, haddock]
macro_assoc : { 
  fish : [flounder, cod, haddock],
  shellfish : [scallop, crab, clam],
  other : [chicken, pig, cow]
}

There is no breakpoint from this loop https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Yaml/Parser.php#L1230
So it collects all lines till the end of file after '{' sequence block start.
I can make PR on this if needed
