“All knowledge must be built upon our instinctive beliefs. If these are rejected, nothing is left. We can organize these beliefs and their consequences, modifying or abandoning them until they don’t clash, forming a harmonious system.” | Bertrand Russell on Epistemology

Based on how he uses it in the argument, I would describe this comment as you need to trust in persistence if you want to make progress.
Alternatively: Last Thursdayism cannot be disproven, but you also won't progress if that's a deal breaker.
Russell claims we can reject Last Thursdayism on grounds of "common-sense", but he admits its weak. Id say even more so in the present day.
Instead I reject Last Thursdayism on grounds of utility. If Last Thursdayism is true, there's nothing I can do about it, so there's no cost in being wrong.
Other names for this problem are Solypsism and Descartes Demon. All different hues of the same problem.
