Boot 2.3.x is no longer supported https://spring.io/projects/spring-boot#support the last release was 2.3.12 last summer.

In any case, Boot 2.3.x uses spring-data-commons 2.3.x (2.3.9 pulls in 2.3.7).

ExpressionDependencies was not added to spring-data-commons until 2.4, so you have some mismatched dependencies somehow.
