8 months ago I am afraid that this happens because the raster is calculated on-the-fly it cannot work with any algorithm that expects an existing ("materialized") layer.
This is certainly a bug: whether we decide to prevent on-the-fly raster to be used as input layers in processing (quick way) or implement a "materialization" function (much more complex) .
What is the bug or the crash?
The raster calculater in the Raster menu gives a layer name/source filename with "illigeal" charcters for "terraen_volumen@1" >= 4 if using "On-the-fly-raster" The filename takes the expression as name both as layer name and in the source. Renaming the layer does not have any effect, because it is the source that are used in further calculations ex. Clip Raster. In the following 3 dialogs I have used the original layer name with the expression layer name. In dialog 4 I have renamed the layer to easy_name, and the run the clip raster. The result/error is shown in yellow.
Steps to reproduce the issue
