Editing big template creates LatteMacroLexer exception and the whole PhpStorm freezes

[vtchkrcn]

Describe the bug
I was rewriting some legacy plain PHP code to Latte template so I pasted the whole code to the template then I added some Latte comments. After that I started editting the code line after line to make it valid Latte file. In that moment PhpStorm freezed for couple of minutes (1:20 according to logs). After unfreeze PhpStorm freezes everytime I try to edit the template. Unfortunately I have no idea which part of the template creates the exception because debugging is very annoying.

I also tried downgrading to previous PhpStorm version and also downgrading to the previous plugin versions but with no effect.

PhpStorm log: WARN - com.intellij.lexer.FlexAdapter - com.jantvrdik.intellij.latte.lexer.LatteMacroLexer
java.lang.Error: Error: could not match input

Environment:

• PhpStorm version 2021.2.2, 2021.3
• Plugin version 1.1.4, 1.1.3, 1.1.0
• OS version MacOS 12.0.1

To Reproduce
Steps to reproduce the behavior (or attach video):

1. Open given template in PhpStorm
2. Edit random part of the template

Code

Additional context
The original code is legacy and really messy - that was the reason to put it in the template.
