Please disregard the calculation that I posted earlier, I took not into account that it was for images with 3 channels.

Below you will find the correct calculation:

-> I have found the threshold image size on which this error will occur only on Apple Silicon macs.
If the image dimensions = dim_x * dim_y  
multiplied with the number of bytes for the float data  = *4
multiplied with the number of channels (1 mono, 3 RGB)
exceeds a size of 1536MB where 1MB = 1024x1024 Bytes
the crash occurs...


So
an image of size 14145x9430 with 3 channels will load, total pixels = 133.387.350 pixels -> bytes ? * 4 * 3 channels RGB= 3 * 1.600.648.200 bytes
an image of size 14196x9464 with 3 channels will not...  total pixels = 134.350.944 pixels -> bytes ? * 4 * 3 channels RGB= 3 * 1.612.211.328 bytes

1536MB = 1024*1024*512*3 bytes = 1.610.612.736 bytes

The size of the float buffer clearly is not the issue, the buffer is created correctly and has the correct size when i try to create the texture.
