Error! Unable to generate Contract ByteCode and ABI (PLEASE HELP)!

Support

Hi guys,

I've been trying verify my first contract on Etherscan. I've managed to deploy it successfully, however I keep getting the error in the title when trying to verify so that it can be interacted with.

I've tried everything I can think of/find online and always get that error.

It's my first time using Remix and coding, and I've been stuck on this final verification part for days, losing the plot! (lol)

Any help would be much appreciated.

Below is my flattened contract & the contract address on Etherscan:
