Hi Michael:
Enhance Compression Wavelet (ECW) is a proprietary compression format.
I would try exporting your image as a geotiff to see if it is being read
correctly and does not have internal write protection on it.

I'm having issues trying to clip ecw images to a mask layer.
Using raster-extraction-clip raster to mask layer.
Default parameters.
The tool runs extremely quickly (successfullyin 0.12 seconds), but
produces a raster entirely black (0,0,0 for all pixels). With the
correct extent of the mask layer.
If I tick the box to create an alpha output band it produces an
entirely transparent result.
Source and mask layers both in EPSG 28350
Anyone else having this issue? I cannot see any bug reports.
Tried in 328.8, 3.28.9, 3.32.0 and 3.32.1 with same result.
Seems to work fine if input raster is a tif.
