What noun or noun phrase do you use for not doing something that you intended to do because subconsciously you did not want to do it?
In speech it is called 'a Freudian slip'.
(Merriam Webster online dictionary) He meant to say "I'm glad you're here," but what came out was a Freudian slip: "I'm mad you're here."
How about in deed and not in speech?
I forgot her birthday, but it was a/an ???.
… meaning that it is no wonder I forgot her birthday as I do not like her very much and, deep down, did not mind hurting her, did not want to please her.
The French word for this is 'un acte manqué', but try as I might I could not find any equivalent in English.

Bash on with using Freudian slip to describe that kind of mistake of the memory or of action. This usage is blessed by Lexico which provides the definition
It then rather undoes it's own definition by failing to provide example sentences using the term to describe errors in memory or action.
If that doesn't satisfy you, maybe you would rather use parapraxis, which Lexico defines as
Other sources provide similar definitions of parapraxis. I think using a posh word like parapraxis is more likely to confuse the average reader than extending Freudian slip to encompass an error in action.
