Root problem discovered and captured in brave/brave-browser#4343

@petemill attempted a solution in #2384

Would be good to know if this happens on Windows with raw 0.65.x branch or if we just got lucky with this PR (causing the conditions that triggered the error)

[simonhong]

Rebased and re-run Builder and only lint check was failed.
I think we can merge this?

[kjozwiak]

Uplift to 0.65.x approved after deliberating with @srirambv. Please ensure that all the correct labels are being used and the appropriate issue(s) are moved into the correct milestone.
