Debug crashes on closing a parenthesis while calling a method with parens and an argument

Your environment

• ruby -v: ruby 3.0.5p211 (2022-11-24 revision ba5cf0f7c5) [x86_64-linux]
• rdbg -v: rdbg 1.4.0

Describe the bug
When in a debug session in the rails console, trying to run a method on an object that requires an argument in parentheses, the debugger crashes with the error:

unmatched close parenthesis: /\Aobject)/ (RegexpError)

To Reproduce
In this exact scenario, I am using a custom validator object that inherits from ActiveModel::Validator. I call Object.create!(arg1: arg1, arg2: arg2) and hit the debugger inside the validate method as expected. At this point, I need to call a class method from the object that is being validated: Object.find_parents(object). When I close the parentheses on (object), I receive the above error. I also tried calling an instance method on the object with the same behavior.

Expected behavior
I would expect the debugger not to crash.

Noticed there was a newer version, and this issue seems to be resolved there. Closing issue.
