Font missing in Figma Web

Hello everyone!

I have a problem with Figma Web where I can’t edit because there are missing fonts. I have tried looking for solutions and reading several topics in the community, but I haven’t been successful.

My main issue is that my MacOS is stuck at 10.15 (Catalina) and cannot be updated anymore, and I do not have any other devices that I can use at the moment. Meanwhile, the Figma Desktop app is no longer accessible because it requires at least OS 11.0, and the Figma Font Agent also cannot be installed due to the outdated OS.

So, is there a solution for those of us still using an old OS? Is there a Figma Font Agent that we can install for older OS versions? Or are there other solutions, such as installing an older version of Figma Desktop that is still accessible?

Please help, as I currently cannot update my OS (the updates have stopped at 10.15) and I am unable to purchase a new device with a different OS.
