Is this gap normal?

That’s normal. Can you post a picture of the tip of the bar?
Does the bar gauge match your chain?

That narrowing at the bar tail is normal as others have stated and acts as a "lead in" for the drive links off the sprocket.
Off the photo provided, it looks to me also that the chain might be narrow gauge for the bar rails- almost looks like the sideplates are inside the outer edges of the bar rails.
Also looks to be quite fine dust rather than chips- might be the chain cutter profile (dull and closed gullet), the "two part" depth gauges and incorrect gauge combined with rail wear, maybe a step at the bar proper to replacement nose sprocket that is allowing fines into the bar rails.
Could also be what you are cutting- if the timber you are cutting is a bit softer than usual, dirty, or just plain rotten- it will throw more dust than chips and help clog things up.

I sometimes have problem with bar groove getting gummed up in very cold weather until I started using the winter grade bar oil or thinning the regular bar oil somewhat with diesel.
I've had to take a putty knife and use the edge and clean the groove really good then thin the bar oil with diesel. I also started using the Stihl winter grade bar oil in the BLUE jug and it does not gummy clog as often.
If the chain is dull making dust it will clog more often.
You also need to make sure your chain is correct for the bar.
If you do not have a mic or tools for checking bars and chains here is a handy Oregon gauge for around $7. (this gauge will also give you an idea if you are using the correct file size for the pitch of the chain)

I recall this photo from a very recent post regarding no oil feed port visible on the tail of the bar. Also recall and can tell by paint that this is a Husky. Are sure that bar isn’t a Stihl bar? Sure looks like one to me. What info is stamped on the tail?
