Opening a Workflow got Knime stuck

Description:
I started in Classic UI and wanted to open this workflow which, even after about 10 minutes or more, never completed. I also did not receive the message that Knime didn’t respond for X-amount of seconds. I was required to kill the process.

PS: It also happened in Modern UI and with another workflow. I added that thread dump as well.

Workflow (37 MB) caan be shared via DM because of client data.

Please mind the thread dump below.

Steps to reproduce:

3.
