Fonts issues v7.0.21

Dear Forum Members,
Sinds a few days I have a font issues in Spectralayers pro. All my fonts on my timeline (project) and timetracker are replaced by weird symbols. The first thing I thought about was a corrupt font in Windows, so I reinstalled all default fonts with fresh ones, but my issue is still there :frowning:
Tried some reset all config within Spectralayers and even did a few reinstalls, but still the issues is there.
Does anyone have any idea? Don’t want to do a complete Windows reinstall …
Thank Patrick
