setPlaybackRate is not working. Changing video's speed is not working.

[ImrozCinchy]

I am using Angular 10 and ngx-plyr 4.0.0 and plyr 3.6.3
When I am adding Google Tag Manager scripts to my project I start receiving below error:

So whenever I try to change the speed of the video, it brings out the same error in console and there is no change in speed of the video.

This is how I am using the plyr in HTML

<div class="mb-20" plyr [plyrTitle]="selectedVideoDetails.title" [plyrSources]="vimeoSources" [plyrOptions]="plyrOptions"></div>

Where vimeoSources is
[{
src: 'Some vimeo url',
provider: 'vimeo'
}]

and plyrOptions: Plyr.Options = {fullscreen : {enabled: true, fallback: true, iosNative: true, allowAudio: true}};
