My swiss cheese plant large leaves are dying
I have had the plant for 35 years. It has moved home and been repotted many times and always thrived. It has been in its existing location in sunny/shady lounge for 5 years. For the last year it has only had small new leaves but now all of the large leaves are going brown, but the small leaves are still healthy. I have not changed anything about its care. It is due to be repotted.

I suspect it has a fungus. Try treating it with a fungicide.
Need for repotting may also be the issue, but typically if this was the case, you would see problems with new leaves rather than old leaves.
