Error on Attempting to Configure Columns in Datatable

[bw-ath]

After copying a screen with a datatable in it, I get the following error when attempting to re-configure the columns. I deleted the copied screen, as well as the original table, and then re-added table with a different name. The error went away, however I went back into the flow the following day, and the error is now appearing again:

We can't launch this flow because of a variable error. Send this error to your admin. The value null is being provided for variable vSObject but isn't compatible with the variable's data type (String). Check the places where you implemented the flow - such as through a Lightning page or a custom button - and make sure that all provided values are compatible with the variables data types.

this error is not related to datatable, it seems that there is a core bug in salesforce which happend sometimes around types. https://trailhead.salesforce.com/fr/trailblazer-community/feed/0D54S00000C4X0zSAF
