</project>

I tried to delete the .idea folder or "invalid cache and restart" but nor the first neither the second approach fixed the problem. There is a similar question Cannot resolve symbol SpringApplication but the answer didn't resolve my issue. how can I fix that?

I fixed this issue by downgrading the maven version.

you need to add dependency 

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.0.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

You are not using SpringBoot parent but your own, you need to add dependency:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-dependencies</artifactId>
    <version>${spring-boot.version}</version>
    <type>pom</type>
    <scope>import</scope>
</dependency>

you seem to use Spring Boot version 1.0.1, @SpringBootApplication annotation was introduced in 1.2
