Thank you for the screenshot, Anna! The missing CoreSync folder would prevent your fonts from being able to sync. Please try making that folder manually to fix the problem:
1. Quit the Creative Cloud desktop application if you have it running, then:
2. Press Win + R to open the “Run” dialog window
3. Copy and paste this string into the "open:" field, then press enter:
cmd /e:on /k md %userprofile%\AppData\Roaming\Adobe\CoreSync
A console window will open and show that a command has been run. Please make a copy or screenshot of any messages that is printed there, just in case we need it.
4. Restart the computer
5. Reopen the Creative Cloud desktop application
Please give that a try, and let me know how it goes! Thank you,
