Grass processing algorithms fail if using raster vsizip input layers. I presume any other vsi*** source would also fail.
I have not checked vector vsizip, but this ticket indicates they are intended to be handled OK: #29001
Could be related to #50588
Steps to reproduce the issue
Get or make a zip file containing one or more geotiffs.
Drag and drop into QGIS and load the layer.
Try to run a grass algorithm which takes raster inputs. It will fail.
e.g. r.patch and r.watershed both fail with this as the key error message:

Additional context
I believe this is a longstanding issue; I thought I filed a ticket for it years ago, but I can't see one anywhere.
