Exception thrown - Using Focus Merge

[freddyhard]

This one is strange one. i attempted twice to run Focus Merge on a stack of 20 photographs. Nothing i wasn't doing yesterday and nothing usual about them. Affinity photo just disappeared, but when i check the Application Logs this exception was thrown.

i ran Focus Merge on another stack of photos and it worked as normal. i then went back to the first set of photos and now it works. The easiest thing is to ignore this, but i thought i'd throw it out there in case someone found it of interest?

 

Application: Photo.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.

Hi @freddyhard apologies for the delayed response,

The Event viewer exception alone won't be enough for us to go off and action anything, Is this a crash that you've been able to replicate using the same set of Images? If you're able to replicate the issue let us know and also provide a copy of the image set you used.

Many thanks!

When that exception was thrown i restarted the PC to try and give Affinity a fresh start. The exception was thrown again with the same set of photographs. This time i just restarted Affinity and tried the focus merge on a different set of photographs with no exceptions. i then tried the set of photographs which threw the exception again but this time the focus merge worked. i have those photographs deleted now and i haven't had that exception since.

In hind sight, maybe i should have kept the photographs for testing.
