Failure happens here:

reactotron/lib/reactotron-core-ui/src/utils/filterCommands/index.ts

Line 35 in 6838133

const searchRegex = new RegExp(trimmedSearch.replace(/\s/, "."), "i")

Constructing a regular expression with new RegExp('[', 'i') is invalid and will throw an error.

This is a result of the simple but naive approach of constructing a regex based on user input. We have a few options to fix:

1. Escape regex special chars
2. Just use something like microfuzz to do searching for us
