Additional context

[PeterPetrik]

can you please try with https://qgis.org/downloads/macos/nightly2/qgis_nightly2_master_20200917_044804.dmg ? The QGIS 3.16 will be release with completely different package mechanism

OT::Coverage::get_coverage is part of https://github.com/harfbuzz/harfbuzz

[PeterPetrik]

could be also strange default qt/qgis font

[PeterPetrik]

can you try mv ~/Library/Application\ Support/QGIS/QGIS3/profiles ~/Library/Application\ Support/QGIS/QGIS3/profiles_bk to start with completely new profile. Harfbuzz is library used by fonts, so I suspect that it could be with some missing, unaccessible font used somewhere...

[gubuntu]

Moving the profile fixed it, thanks (through now I have to start again with a blank profile)
