In process/export/ExportLarge2DTIFF.java, line 36 imports ch.epfl.biop.kheops.ometiff.OMETiffPyramidizerExporter, which was renamed to OMETiffExporter in this commit in 2023.
As a result, when using BigStitcher, I get java.lang.NoClassDefFoundError: ch/epfl/biop/kheops/ometiff/OMETiffPyramidizerExporter .
The workaround is to revert to ijp-kheops-0.3.4.jar.
