Hello.

%subj%, there's not much to add here.

The problem has been already discussed here: https://newsgroup.xnview.com/viewtopic. ... 58#p203758
Seems like heif.dll doesn't use dav1d again.

The bug has been already fixed (twice) and re-appeared also twice, the last time it was fixed in 1.8.6 and re-appeared in 1.9.0.
