Error 86::1 After Effects 2020 in Windows 10

I've done everything through the After Effects CC 2020 program.

I am using Windows 10. And I never deleted the codec or the Quick time player.

However an error occurred while I was rendering through Adobe Media Encoder

So I ran the after effect. And found an error message.

"After Effects error: the source compression type is not supported (86 :: 1)"

"After Effects error: file '# 2 snow BG.mp4" cannot be imported? this '.mp4' file is damaged or unsupported.

"After Effects error : Could not open source file. Please check that file exists with correct permissions. (86 ::1 )"

About 20 types of error messages have been found

I tried various methods because I could not understand, but failed.

1. All auto saved files have the same symptom.

2. Importing the source again produces the same error.

3. After importing the new After Effects, there is no problem.

I had done everything. Suddenly this happened to me.

I want to cry The project is no longer able to proceed.

I need great help, and this message was written through Google Translator


--------------------------------------------

I solved the problem through the help of others

The problem was After Effects CC 2020.

No problem after running with After Effects CC 2019

I hope you know the CC 2020 version is very bad.

I was very disappointed with this version and had many other issues.
