ChatHandler giving console error with custom chat prefix containing square brackets.

[Garwinium]

HD Admin version: 1.31.8 (newest version according to HD Admin itself)

The error being given:
"ReplicatedStorage.HDAdminHDClient.Modules.ChatHandler:79: malformed pattern (missing ']') "

This error is given on every new chat message.

My script:
(If being copied for testing, the condition that checks if a player is muted via an "invisleaderstats" folder should be removed)

local TextChatService = game:GetService("TextChatService")
local Players = game:GetService("Players")

TextChatService.OnIncomingMessage = function(message: TextChatMessage)
	if message.TextSource == nil then return end
	
	local properties = Instance.new("TextChatMessageProperties")
	local player = Players:GetPlayerByUserId(message.TextSource.UserId)
	
	if player.invisleaderstats.Muted.Value == true and player ~= Players.LocalPlayer then
		message.Text = ""
		properties.Text = ""
		message.Translation = ""
		properties.Translation = ""
		message.PrefixText = ""
		properties.PrefixText = ""
		return properties
	end

	properties.Text = message.Text
	properties.Translation = message.Translation
	message.PrefixText = ""
	properties.PrefixText = "[@" .. player.Name .. "]:"
	
	print(properties.PrefixText)
	
	return properties
end

Removing the square brackets from the PrefixText causes the console error to no longer appear.

I believe this is because string.Find() uses square brackets as part of patterns unless they are preceded by "%"

I have also experienced a possible issue where it overwrites custom prefixes that do not include a player's display name (such as my example where it instead uses their actual username)

However, this second issue is intermittent and I haven't been able to consistently replicate it, and the "condition" may not even be the prefix/display name thing.
