Mosaic to new raster crashes ArcMap

[JanisMitkovs]

Hello!

When I'm using Mosaic To New Raster tool it crashes my ArcMap without any error. I need to compress several tif fails into one tif dataset. I have done this many times before without any problems, but recently I can't compress even two images. I tried running the tool both with background processing enabled and disabled.

I'm using flowing parameters:

• Pixel Type - 8 BIT
• Cellsize - 0,5
• Number of bands -1
• Mosaic operator - LAST
• Mosaic colormap mode - LAST

My ArcMap version is 10.6.1
