I was performing the collocation of various bands of ALOS-2, Sentinel -2 and Sentinel -3. The collocation took 7 hours and 25 minutes.
The image failed to open and there was an " Failed to open image view null " Error.
What is possibly the mistake ?

That’s difficult to say.
The stack trace indicates that wither the vector data node is not contained in a product or the vector data node itself is null.
How big is you collocated product in terms of GB?
Can you provide it by e.g., WeTransfer?
Maybe you can fix this by removing the masks in the Product Explorer. Of course, only if you don’t need them.
Had a similar problem when importing a shapefile as a vector and using it as a landmask via Land-Sea-Mask as part of a gpt processing graph.
Trying to open a band of the resultant .tif in SNAP 10 GUI resulted in the error below.
Deleting the shapefile in the Masks folder solved it, and I can see the bands now.
