Text disapear when adding video

Hello,

When I add a YouTube video to one of my recipe, the ext disappear instantly. I remove the video, the recipe is back to normal. I tried removing the loco translation I did, and disable the autoptimize cache plugin without success. I think it was functioning for a while but I cannot understand what changed except those two plugins.

Anyone got an idea ?

Regards,
