java.lang.AsserationError when importing sbt project

Hello!

Thank you for reporting this!

Would you be able to share the Project or IDEA's Logs (Help → Collect Logs and Diagnostic Data), so we can take a closer look at the issue?

Here is a link to the file with all of the IDEA logs.

Thank you for sharing the logs!

Unfortunately, it seems that this particular error is not getting logged - may I ask you to to paste the full error message in text format, instead of a screenshot?

As a workaround try the following:

1. Close all instances of IDEA
2. Rename or remove the System Directory

If the issue persists, could you please share the affected Project?

Here is the full error message

Thank you for sharing the error message!

The issue appears to be fairly unique.

Would you be able to share the affected the Project or, if that is not possible, put together a small reproducer Project with minimal code, that exhibits the same behavior, so we can further investigate this?
