I was going to edit after just downloading and paying for after effects 2k22, it went well at first but then it just crashed and now it wont allow to access it . I don't know what happened or how to fix it. Please help.
Without any system info and other technical details liek actual crash info we can't tell you much. As already advised, start by rebooting your computer and attempt to reinstall AE. Also delete any preferences and otehr configuration data that may be tainted and prevent a successful launch.
