I will try to take a closer look at this later today.
Can you please check if you still get the crash with a smaller texture size. I believe using a texture size of 8192 x 8192 is resulting in some memory issue which would be affected by system resources available on your system.
Like I said, I will look into this but I would recommend using atlas textures that are no larger than 4096 x 4096 and possibly no larger than 2048 x 2048 as this is the maximum supported by still many mobile devices.
I’ll take a closer look today with that font as a crash with smaller texture would be a different potential issue.
Do you get this crash with any characters that you are trying to add or specific ones? If specific ones, can you provide me with those characters or unicode values of these characters?
