Hi @wplmillet, thanks for opening this ticket!

Can you enable WP_DEBUG in your site's wp-config.php file? This will reveal some more details for the error.

This line can be used to enable WP_DEBUG:

define( 'WP_DEBUG', true );

You may already have a line that says define( 'WP_DEBUG', false ); - you can just change false to true in that case.

If you can then repeat the steps to produce the error, and drop the more detailed error message here, that would be great!

(Afterwards, you should set WP_DEBUG back to false)

I'm on playground . So what is the method to retrieve the log ?
In an other test, i see that :
if I go back to the font library upload tab, the font appears in the list under library but not in the list in the side column.

I don't think Playground allows accessing the logs.

This looks more like a Playground issue than an issue in the font library itself. I cannot reproduce this locally on a development site nor with wp-now (which uses Playground under the hood).

Therefore I'm closing this issue.

if I go back to the font library upload tab, the font appears in the list under library but not in the list in the side column.

It will only show up once you activate the font. In your screenshot, 0/2 variants are active
