No longer works after updating extension to 1.2.0, chain-crashing

[filliph]

The PHP Language Server server crashed 5 times in the last 3 minutes. The server will not be restarted.

[Error - 4:13:02 PM] Connection to server got closed. Server will not be restarted.

What information do you need in order to resolve this issue?

[felixfbecker]

A stack trace at least. Have you checked the dev tools?

I didn't know how to open dev tools, I worked it out.
