Offer latter withdrawn after serving notice period from previous organization - Commercial Manager Blue Star Employee Review

I was given offer latter & I was supposed to join Bluestar after serving notice period in other organization. In between, company has withdrawn my offer latter citing reason of revenue shortfall & cash flow issue during lockdown. Due to bluestar, I remained unemployed as I have left current organization & bluestar had withdrawn offer latter. I feel that it was my worst decision to join highly unorganized company like bluestar.
