Hotseat disappears for no obvious reason

[anotherboringuser]

Hello,
Sometimes the hotseat on my phone disappears entirely. It appears again after restarting the launcher or it comes back on its own. Could someone help me to fix this problem? Does anyone need any information?

Does the same for both of my phone's, common factor appears to be when I open the camera, especially if I open the camera from lock screen.
