https://invent.kde.org/libraries/ktextaddons/-/commit/b4118821a61ee8b15cce234e7d85aba97584e16b broke ABI compatibilty between 1.7 and 1.8. At a minimum, ruqola needs a rebuild in f43+, but the PIM suite also uses it extensively, and there may be other breakage as well.
Ruqola is already in my list of rebuilds because of the changes in plasmaactivities. The rest of the pim suite isn't though.
But yeah, let's reevaluate after we are done moving everything to 6.10
