I did not have this problem when building the 6 AppImages today but that is because I have had this error in my build log for some time and never knew how to fix it.  Not even sure when it started but it was in 2021 or 2022 -- I will narrow it down to see which change created the issue and let you know.

For some reason libtiff was erroring out for me on first build for both debian 11 and ubuntu 16.04

I think this patch to libtiff itself fixes it, but then it was working if I remove libwebp and rebuild it ....

strange, strange.
