Problem with Google Font 'Vollkorn'

Problem with Google Font 'Vollkorn'

[Michael Urban via ntg-context]

I downloaded the Google free font ‘Vollkorn’ (https://fonts.google.com/specimen/Vollkorn) into an appropriate directory and ran 
 mtxrun --script font --reload 
all went well, and the Vollkorn truetype fonts show up in the output of mtxrun --script font --list --all   .

However, the following input:

\starttext
\definedfont[name:vollkornregular*default at 14pt]
\input tufte
\stoptext

fails, with the following output:
system       > ConTeXt  ver: 2020.03.10 14:44 MKIV beta  fmt: 2020.6.8  int: english/english
      
fonts           > otf loading > loading 'MYPATH/texmf/fonts/truetype/google/Vollkorn-Regular.ttf', hash 'vollkorn-regular'
fonts           > otf loading > loading failed due to read error
fonts           > defining > forced type 'ttf' of 'Vollkorn-Regular' not found
fonts           > defining > font with asked name 'Vollkorn-Regular' is not found using lookup 'name'
fonts           > defining > unknown font 'Vollkorn-Regular', loading aborted

This is on Mac OSX.   I don't recall this problem coming up before.  Evidently the difficulty is that it is expecting an otf font and is confounded by the truetype file.   

The ConTeXt font system always bewilders me, but this time it's pretty specific.  Help?

For me it works on MacOS 10.14 and ConTeXt LMTX 2021.10.28.

Does your list look like mine?:

$ mtxrun --script fonts --list --all --pattern=vollkorn

Hi Michael,

I would rather wipe out the cache and start again:

 mtxrun --script cache --erase && mtxrun --generate

I had problems reloading fonts on Linux, so I always run that after
updating ConTeXt or adding a new font.

Just in case it might help,

Pablo
