VistasCannot access script base class 'org.gradle.kotlin.dsl.KotlinBuildScript'
When I create an empty project with Gradle Kotlin DSL, even without any modifications, it would prompt Cannot access script base class 'org.gradle.kotlin.dsl.KotlinBuildScript'. Check your module classpath for missing or conflicting dependencies The project can run, but the syntax highlighting and autocompletion for build.gradle.kts don't work.
What I've tried

- Changing gradle executable to
gradle-kotlin-dsl-5.2-20190122225509+0000-all.zip
- Changing gradle executable to

The syntax highlighting feature worked after:
- Delete
~/.gradle/caches - Delete
~/Library/Application\ Support/Library/JetBrains/IntelliJIdea2020.3(or~/.cache/JetBrains/IntelliJIdea2020.3for ubuntu/linux users) - Delete
<project dir>/.gradle - Delete
<project dir>/.idea - Start IDEA and reimport the project.

Worked for me after I'd deleted:
Delete <project dir>/.gradle
Delete <project dir>/.idea

In my case (the OS is Windows 10) it was enough to:
- Delete
C:\Users\<you>\AppData\Local\JetBrains\IntelliJIdea2021.1\caches - Restart IntelliJ IDEA.
- Click "Load Script Configurations" when it appears after re-indexing.
Thanks @MichaelBöckling for a hint!

For IntelliJ 2021.1, I had to delete the caches folder at:
~/Libary/Caches/JetBrains/IntelliJIdea2021.1/caches

I set the project SDK to Kotlin under Project Settings > Modules. I also set the SDK in Plaftorm Settings > SDKs although I don't know if that's required. And just in case I restarted IntelliJ with File > Invalidate Caches / Restart ...

In my case, I had to install the previous IDE version (2021.1.3).

Mac OS:
- File -> Project Structure -> SDK Location -> click on Gradle Settings
- Modify the Gradle JDK
- File -> Invalidate Caches...

Guided Cache Recovery (IntelliJ IDEA 2021.3+)
IntelliJ IDEA versions from 2021.3 and on (as of writing, available from JetBrain's Early Access Program, or EAP) has a featured called "Guided Cache Recovery" (File, Run Guided Cache Recovery...). While I can't find any documentation yet about this feature, it appears to give the user the ability to apply diagnostic/recovery steps, one at a time, to fixing any cache issues.
For me, the problem reported by the OP was resolved at step 2: "Rescan Project Indexes".
The really cool thing about this is that, not only did it fix my problem, but IntelliJ then created an issue report with details about the problem found, and gave me the option of submitting this report to JetBrains via the crash reporter. This tells me that JetBrains appears to be serious about fixing these issues for users, and about resolving their root causes.
Permissions Issues in .idea, .gradle, or gradle
Another possible problem is permissions issues in one of the .idea, .gradle, or gradle directories. For example, running a rootfull docker container, mounting the project as a volume (for example, to run a tool like Qodana) could cause some files to become owned by root unless the appropriate Docker options are used. If this issue is noticed, reset permissions with chmod and chown and then sync again in IDEA.
