@tim_w_photography apologies for the delay in figuring this out, but this may solve your issue:

Can't Launch Latest PhotoStructure Alpha

Howdy @tmeitner and welcome to PhotoStructure! Thanks for taking the time to report this. PhotoStructure should be statically compiled, but it looks like the alpha.7 build linked to the system libvips.so library instead. Assuming you’re on Ubuntu 20.04 or later, if you run sudo apt install libvips42 and then try again, it should launch. If it doesn’t, please tell me! I’ll fix this in the next build. Apologies for the hassle!

I’m about to release alpha.8, so either way, if it works or doesn’t, I’d be interested in knowing.
