VS code window freezes when using regex search

[andreihrs]

Type: Bug

I was trying to find all occurences of a specific object in a JSON file of 1000 lines, but the window freezes randomly when I use the regex search feature

I did upgrade to a newer version and it looks like for a 300-line JSON file, I don't incur the same freeze. Not sure if it's going to happen on a bigger file, will update

[andreamah]

Does this happen on any regex? Or a specific one?

I found the same issue. Here is how to reproduce: 1) go to vscode.dev in the browser 2) create new file and paste content of https://raw.githubusercontent.com/prisma/database-schema-examples/main/mysql/magento/schema.sql 3) press CTRL+F or CMD+F, enable regexp search. 4) search for CREATE TABLE([^;]|[\n])*([^;]|[\n]); 5) change regex to CREATE TABLE([^;]|[\n])*`([^;]|[\n]); by adding a` between * and (

Chrome tab freezes

Tested on up-to-date mac, in up-to-date chrome, on vsdoce.dev
