Bearing on leadscrew loose

I was having multiple print failures on something I knew printed fine with same settings. I went and did maintenance steps and noticed the left side leadscrew was loose and the bearing popped out.

I tried getting bearing back in, googled this and shared on a discord server. No one I’ve found had this issue. I opened a ticket and it’s been three days. I need to get some stuff printed to fix other printers.

Anyone have an idea? Have taken off bearing and tried to get it back in. I can’t add the video.

Left side Z-axis screw upper bearing?

Yes. Left side. The bed pops up and down.
