My Timeline is broken

My timeline is too small cause if i put any file in there it isnt visible. I’ve tried to resize it with the dots under ‘project’ but it wouldn’t resize.I also tried to reset the layout to default but the timeline would still be the same. The scroll thingy is also microscopic. I don’t know whether im doing someting wrong or this is a bug.Please help

What happens if you close the keyframes toolbar (hit the X at the bottom right of your window. Does the timeline now appear?
