Can't export large albedo map

[Entropy159]

I'm trying to download a high-resolution map for use in Terragen, so I selected the area and exported a 16K resolution heightmap and albedo. The issue is that when I render it, the texture looks blurred because it's too low resolution. However, I cannot export anything higher, even with the tiling, because it either runs out of memory or spams 404 errors in the console. Do you have any ideas on how to solve this?

Can you give me an example of where it's not working?

You can copy and paste the URL here to show me the parameters and area you're using.

Which map source are you trying to export?

Sorry for the late response! Here's the link: https://manticorp.github.io/unrealheightmap/index.html#latitude/41.30257109430556/longitude/-111.97402954101562/zoom/10/outputzoom/16/width/32768/height/32768/outputformat/png16
I also have it set to tile by count, with a tile count of 2 for each side, and the map preview type set as USGS US Imagery. The issue arises when I export the Albedo map: it starts to stitch the tiles, but once it gets close to the end it stops and the progress bar goes away entirely. When I check the log, it shows this error:
RangeError: Failed to execute 'getImageData' on 'CanvasRenderingContext2D': Out of memory at ImageData creation.
