I don't think I provided all relevant information in my previous post with a similar title.

The conclusion in that previous topic was that I can keep doing what I'm doing and don't have to fear losing the reward if I find a block.

I want to provide more information and see if that's indeed the case, since elsewhere (e.g., link below) it is suggested that I will lose the reward if I find the block given my setup.

I think the assumption in my previous post was that I was using a non-SegWit compliant full node e.g., before  Bitcoin Core 0.13.  I am not.

I'm mining using a SegWit-compatible full node, Bitcoin Core 0.18 and wallet, and I'm using non-SegWit compliant pool software, NOMP.

Mining with this setup, will my block be considered invalid and I lose my reward?
