Using 10.37 without JIT:

printf '%s\n%s\n' '/\\([^\\]+)\s*$/'
'App\\Domain\\Repository\\MetaData\\SomethingRepositoryInterface' | pcre2test
PCRE2 version 10.37 2021-05-26
/\\([^\\]+)\s*$/
App\\Domain\\Repository\\MetaData\\SomethingRepositoryInterface
0: \SomethingRepositoryInterface
1: SomethingRepositoryInterface

Using 10.37 with JIT:

printf '%s\n%s\n' '/\\([^\\]+)\s*$/'
'App\\Domain\\Repository\\MetaData\\SomethingRepositoryInterface' | pcre2test
-jit
PCRE2 version 10.37 2021-05-26
/\\([^\\]+)\s*$/
App\\Domain\\Repository\\MetaData\\SomethingRepositoryInterface
No match

Using 10.36 with JIT:

printf '%s\n%s\n' '/\\([^\\]+)\s*$/'
'App\\Domain\\Repository\\MetaData\\SomethingRepositoryInterface' | ./pcre2test
-jit
PCRE2 version 10.36 2020-12-04

App\\Domain\\Repository\\MetaData\\SomethingRepositoryInterface
0: \SomethingRepositoryInterface
