error when opening a workflow

Hello, I have a problem when opening a workflow that I have always opened with a .knwf extension for a few days, it does not allow me to open it because it generates the error:

java.lang.NoSuchMethodError: org.knime.core.node.workflow.WorkflowContext$Factory.setMountpointRoot(Ljava/io/File;)V

I have KNIME version 3.2.0

The operating system is Windows Server 2012 R2.
