I'm not sure how you could have a Dyson swarm without first having a Dyson Sphere, and then having the technical aspects of that resolved by a constellation of satellites. The collision part is really more of a Kessler Storm which would be the rapid deterioration of a Dyson Sphere / constellation of satellites, rather than a Dyson Swarm. But I'll go with that for my conclusion of what you meant.
In any case, yes, constructing such a sphere, or even a constellation of satellites would be a very risky proposition indeed! I would put the probabilities of success down in the single digit range of percentages. You're 100% correct.
Several probes have been put into orbit around the Sun, Helios 1 and 2 back in the mid '70's, Ulysses in the 90's, and the Parker Solar Probe in 2018. Of all of these, the Parker Solar Probe came the closest to the Sun, but it couldn't remain there for very long. It then had to cool off by its orbit taking it out to beyond Venus and using Venus for a gravity assist to accelerate it for each successive pass around the Sun. The Parker probe got within 4.5 million miles of the Sun. A Dyson Sphere would have to be smaller than this simply because of the logistics of building something upwards of 9 million miles in diameter (wow! that's even hard to type!...9 'million' miles!), especially when you consider the Moon is only 293 thousand miles from Earth. Just to put this into perspective, this would make it 37x larger than the radius of the Moon to Earth. To put it another way, this would make it approximately 1/10th of the way to Venus in size from Earth. Wow!! I just did some of the math and when I saw that number I was like..."Holy CRAP, that really IS big!!" Just imagine something so big it not only includes the Moon, but even goes 36x further than the Moon! Even still, that's a radius from the Sun at which no material ever developed by mankind can survive the constant exposure to the intense temperatures and radiation which would be experienced at that distance.
Crazy, huh??
