JUnit Jupiter 5.10.0, failed to discover tests

Question

After upgrading junit-jupiter-engine from 5.9.3 to 5.10.0 I started to get the following error. I'm running a Spring-Boot 3 application (spring-boot-starter-parent version 3.1.2).

And from running on IntelliJ, I get:

After some testing, for me it stopped when I added the dependency to spring-boot-starter-tests and removed the dependency to junit-jupiter-engine, but keeping the dependency to junit-jupiter.

My final pom.xml has the following dependencies:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter</artifactId>
    <scope>test</scope>
</dependency>
