Looks like this is a test only crash.

It is a test only crash. This is happening because the resources file is out of date so it's calling a test function that shouldn't be called. The fix would be to update the resources files.

ClusterFuzz testcase is flaky and no longer reproduces, so closing issue.

If this is incorrect, please add ClusterFuzz-Wrong label and re-open the issue.
