Thank you for writing. It looks like the plant has too much sun in that the problem seems to begin with brown tips rather than brown spots.
Spider mites, mealy bugs and scale and fungus is also possible.
Here is information on brown spots https://hgic.clemson.edu/factsheet/palm-diseases-nutritional-problems/
I suggest cutting off dead leaves with a very carefully cleaned scissors, moving it to less light, and spraying it and the soil with an organic soap. I might be more specific with tight closeups of the top and bottom of a leaves in the very early stage of the process.
Best of luck
