What is happening to my tacca bat flower? It’s browning and a leaf is yellow.
I keep it in around a 60° room on a window sill that gets little indirect natural light, and I water it once a week. The browning began about 2 weeks ago and the yellowing 1.

These are, technically, orchids. They will appreciate a much lighter soil than most houseplants. I believe that your soil may be too heavy and rich.
I would put this into a proper mix of orchid mix and potting soil mixed together. Make sure that the mix never gets soggy, but never dries out. This is the problem with most potting mixes. They are too heavy and will get too wet when you water.
