It's a bit hard to tell from that photo, but just generally I've found this to be an excellent resource for diagnosing print quality issues and potential solutions:

In particular for this print, you might find the "Layer separation and splitting FDM" and "Layer shifting" sections helpful

It's managed to get beyond 200C this time! But it did fail at 190°, though that's the low end of the temp range anyway.

Back looks... Okay. I'm assuming that's the Z-seam on the inside of the arch. Bridging looks best on 220°, and I don't know what the deal with that line in the middle of 215° is, best guess is under extrusion by way of friction but idk. It broke apart right where it thins out between 205° and 200° too, so that might be my lower bound.

Even if it looks well sealed, it still could be humidity and popping sound usually means wet filament. That being said, you didn't mentioned if it was pla/petg... Guessing it is pla due to the temp you are using but always best to mention it. Have you watched the print ? Did it actually change temp while printing? because between 190 and 220, there is usually more difference than what you have here, especially on the bridge part.

PLA can tolerate quite huge range od tems. Thats why this test is not best IMO. I found better to print single wall cube with no bottom and no top (also changing temp every 5 mm of height). That way you can see how it looks, but you can also test layer bond by breaking the part with fingers. It is also much faster print.

Just my 0.02

Be sure to apply that script to actually change the temperature. There is not really a change visible. Also the extrusion stops when printing the digits. That's weird.
