Dear list, I like to use the Iosevka as mono typeface. It worked in the past, but sadly context crashes now with the following error. fatal error: /font-dsp-macro.lua:2336: attempt to index a nil value (local 'sequence') Plese see MWE below. Any ideas how debug / solve this issue? Thanks in advance.
