I have tiff imagery files for a Hexagon aerial imagery flight for Cowlitz County, WA.
I want to create a tile package for offline use in field maps.
I am using these instructions as my reference:
https://enterprise.arcgis.com/en/server/latest/publish-services/linux/share-imagery-as-an-arcgis-online-tiled-map-service.htm
I am working in Arc Pro 2.9.2.
So far I tried Mosaic to New Raster but got the Error code 99999.
Then I tried Create Raster Dataset (that I could use for my output raster). Then I tried Mosaic but ArcPro crashed a few minutes after I clicked run.
Then I tried clicking on the Imagery tab and creating an imagery workspace and importing the photos but the tool didn't recognize the photos, so that didn't work.
Here are some screenshots:
This is the grid index for the images:

There are 2,326 images and the file size is 150 GB


Here are the image properties for one of the images:


Here are the settings I used on Mosaic to New Raster:


and the error message:

Create Raster Dataset settings( this worked):

Mosaic settings (ArcPro ended up crashing after a couple of minutes):



I attached the imagery metadata too.
Thank you in advance for any advice, I really appreciate it!
