Thanks for the report. Looks like you are using a custom render profile. Can you please paste here the parameters ( they appear in the render dialog at the bottom of the right column, beneath Audio).
Do you get the same freeze with a standard render profile?

Something like this?

ab=320k acodec=aac ar=44100 channels=2 display_aspect_den=9 display_aspect_num=16 f=mp4 frame_rate_den=1 frame_rate_num=60 height=720 movflags=+faststart preset=veryfast progressive=0 real_time=-1 sample_aspect_den=1 sample_aspect_num=1 threads=0 top_field_first=0 vcodec=h264_vaapi vglobal_quality=0 vq=0 width=1280

I don't know what values the "default render profile" is or was set to.

And even after a crash of Kdenlive ("reset") I never had to change anything in the values for rendering.

I could render before the "sudo flatpak update" command in the terminal, but not afterwards. It is therefore extremely unlikely that a previously functioning "user-defined render profile" is now suddenly the cause.

I must also point out that the command "sudo flatpak update" was executed incompletely. 

Perhaps there is a connection? 
I have reported this bug separately (https://bugs.kde.org/show_bug.cgi?id=491386)
