What if it becomes clear on the Day of Resurrection that I pronounced a vow, and it was not a matter of doubt or obsessive thoughts, will I be held accountable for consuming unlawful wealth, or will I be absolved because I relied on the principle, "Doubt concerning a vow is not to be considered"? And what are the proofs for this jurisprudential principle? And is it a preponderant or a weak opinion?

The principle "certainty is not dispelled by doubt" is a major jurisprudential rule supported by numerous pieces of evidence, including the Prophet's (peace and blessings be upon him) saying: "He should not leave until he hears a sound or perceives a smell." Whoever acts upon this principle will have their conscience cleared in this world and the Hereafter, and they will bear no sin or responsibility before Allah Almighty, even if the matter in reality turns out to be otherwise. This is undoubtedly correct, and it resolves many problems, especially for those afflicted by obsessive doubts (waswas). There is no better cure for them than to ignore and disregard them. So, whenever you doubt whether you made a vow or not, base your decision on the original state, which is that you did not make a vow, and that the original state is the clearness of your conscience.
