Problem with playback of AVCHD 3D videos

I recently got a new Windows 11 PC and installed K-Lite Mega Codec pack, which I have been using for many years.
I now have a problem playing AVCHD 3D files using MPC-HC. I don't have any special 3D capable monitor, so I just expect to see a 2D video. They play just fine with the new Windows Media Player (as normal 2D video), but MPC-HC (my default player) shows a picture like this, which hardly has any motion:


Normal AVC video plays fine, also interlaced video.

This is the media info for one of those files:

I already tried to find some setting that could be responsible for this, so far without luck.
Does anybody know this problem, and has anyone found a solution?

Can you upload the file for me? Then I can check if it works here.

You should try with MadVR as video renderer.

Thanks for the reply. the file is here. I already tried MadVR, without success.

As a workaround you can delete libmfxsw64.dll file in LAVFilters folder. That is the 3D MVC decoder plugin. I suspect that it maybe doesn't work properly with interlaced video. Once deleted the video will be decoded as normal H.264 and the stereo video channel is ignored.

Thanks! That did it. I do have several copies of that library on my system. The version in the LAVFilters folder is 8.18.6.8 from 8-6-2018, but I also found a more recent one (9.19.5.17 from 17-5-2019). Unfortunately replacing it with that one also yields the same problem. So, I guess I'll make do without it for now.
