Cannot load Filament MK3S+

My wife and I just finished assembling our MK3S+ kit and it ran successfully through the self-test the first time. Awesome!

However when it is time to load the filament for the first time it doesn't work - it hits something solid that doesn't yield in the first few millimeters, well before it gets to the gear and idler. My recollection is that's where the steel ball would be in the out-of-filament sensing system. I push reasonably hard in various orientations, and the filament I am using is the silver filament which came with the machine, and I have a 45 degree cut at the end. When we were assembling it we were able to push the filament through the gear.

Frustrating! Any suggestions about what the problem might be and how to resolve it, or otherwise what the least invasive way to get to the problem would be?

I would open the idler door and look to see where the filament stops.  If that fails, disassemble and follow the directions slowly.   You will get past this.

I would take the filament sensor cover off. That way you can push the filament straight into the part with the steel ball. And maybe see where it hits something.

Taking the filament cover off, lifting the idler door, etc. didn't help. We ended up loosening several of the screws on the extruder body and that did it. Although I wouldn't have said any of the screws were overtightened, I guess one or more of them must have been and something was flexed enough to prevent the entry of the filament into the body. I was not looking forward to disassembly and reassembly!

Went through the calibration and ended up with a very clean Benchy. Thanks everyone for the suggestions.
