Spring Kotlin 2.2.20 - Unexpected AOP exception

Info:

Kotlin: 2.2.20 KSP: 2.2.20-2.0.3 Spring Boot: 3.5.5 JDK: 21

Description

When upgrading Kotlin from 2.2.10 to 2.2.20, and KSP from 2.2.10-2.0.2 to 2.2.20-2.0.3, and no other changes, I am getting a new error on startup

(i tried downgrading ksp to 2.2.10-2.0.2 and the error remained, so it seems related to kotlin rather than ksp)
