imported GIF/APNG files will only ever playback correctly once and then freeze until the clip is manually reloaded. This also affects renders where if a given GIF/APNG clip is in the timeline multiple times it will only render the clip once and the others will not be animated. STEPS TO REPRODUCE Import a GIF/APNG File and insert it into the timeline. Playback the GIF/APNG File and after that all additional playbacks of the GIF/APNG will not be animated. OBSERVED RESULT GIF/APNG files only animated correctly once and after that the clip will be frozen on one frame until the clip is reloaded by the User. EXPECTED RESULT GIF/APNG should animate every single time they are played back SOFTWARE/OS VERSIONS Windows: 10
Thanks for reporting. Please upload here the GIF/APNG file so I can test if this is only a Win10 or a general issue.
Created attachment 122249 [details] A sample GIF file affected by the bug. Here is the GIF file I used when testing the bug.

I would also like to mention that I encountered the bug on 2 other systems. One of them has Manjaro Linux installed and the other has Windows 7. I think the Manjaro one wasn't on the latest version (I think it was on 18 rather than 19.04) however the Windows 7 one was using the latest version.
Thanks for uploading the animated gif. Yes I confirm the issue that the animated gif is not playing properly. It should import and show with 500x451 pixel and 20 frames as a normal clip. In Premiere CS6 it works. It seems that Kdenlive doesn't convert the animated gif to a clip. I opened issue https://invent.kde.org/kde/kdenlive/issues/335
You can use following workaround: convert the gif with alpha: ffmpeg -i original.gif -vcodec qtrle output.mov and use the mov file instead.
