    After some debugging it seems removing these lines from my arb is fixing the crash:

    "profileType": "{level, plural, =0{Novice} =1{Not bad} =2{TODO} =3{Gamer} other{True gamer}}",
"@profileType": {
  "placeholders": {
    "level": {
      "description": "The level. Starts from 0",
      "format": "decimalPattern",
      "type": "num"
    }
  }
},

    @thkim1011 it seems like this no longer affects the master channel with the new parser, is that correct?

    I think this may be a bug. Technically, the =3 or three case is not valid syntax, but I forgot to handle this case. I'll make a PR with a fix.

    @rares45 you might want to consider using a select case instead as follows:

    "profileType": "{level, select, level0{Novice} level1{Not bad} level2{TODO} level3{Gamer} other{True gamer}}",
"@profileType": {
  "placeholders": {
    "level": {
      "description": "The level. Starts from 0",
      "format": "decimalPattern",
      "type": "String"
    }
  }
},

    and use the string with LWLocalizations.of(context).profileType('level$level').

    Currently, it will throw a syntax error if numbers are used for select cases instead of alphanumeric strings, but I'm working on a fix for this as well.
