Source stream error

[Peter26069206p1qk]

Hello,

everytime I try to start After Effects 2021 (18.6.4) I'm getting the following message:

"After Effects Warnung: Unknown BIB Error, source stream error, CT, 0

(83 § 3)"

After Effects isn't starting.

Is there anybody, who can helb me?

This eitehr means that you have a "bad" font that is messing up the interface or one of the CoDecs is busted. Delete the preference file, reinstall the program, weed out any fonts you don't need.

If you have any PostScript Type 1 Fonts installed on your system, they may cause this error. Deleting the fonts should resolve the issue.
