That's the file, but please send the entire folder "Goblin Burrow Manager" as unity creates log files in it with more details that could come in handy.
As for sending them, I can recommend the https://wetransfer.com website where you can input my support email happypillowhelp@gmail.com or if you have a discord account then you can join the channel here: https://discord.gg/zqEJKBmZ and send it to me in priv message.
Thank you
Edit: Or just send as email attachment, I completely forgot that they can do that xD
