And these are the same quantum computers that will eventually break ecliptic curve cryptography? Now I’m very confused.

Hasn't classical already severely crippled ECC because of some mathematical Assumptions that somebody came back in 2022 and Proved were wrong?

Not in general, no. It is still secure and used. There are of course attacks but those were not completely breaking
