Serious BUG - Error when opening a workflow - Nodes corrupted/Missing

Dear all,
I think there is serious bug in the last version of knime. While opening the workflow I have an error and then most of the nodes of the workflow disappear. This is the 3rd time that append with 3 different workflows on 3 different computers with different Windows OS. Two of this workflows were very small but 1 was was very huge (I spent several weeks to build it).
Please find attached the error, the log and the printscreen.
I cannot attach the workflow because it contains sensitive data.
Please do something

This is the error

Thank you for the report, we’ll have a look into that.

Hello. I experienced the same issue described in the post above in a workflow I generated in the past week. It does not allow me to keep on working on my file. I hope it can be fixed as soon as possible. Thanks

I just had a look at the log file and it indicates that the files in the workflow directory are corrupt. I can’t say why that is. The log file only contains details on the problems while the workflow was loaded. It does not contain the information on what happened while it was saved (in particular no error messages that may have been reported while it was saved). So it’s impossible to diagnose this.

Can you have a look at one of the settings file and see if they are OK. For instance, this is supposedly a corrupted file:
F:\VD\knime-workspace\adc\NameMatchingEmail\EmailNameMatching_v4\Cell Splitter (#21)\settings.xml

Hope this helps;
Bernd

I am closing this one here and we can continue the discussion here: Error when opening a workflow
