In this work, we realized a collisionally stable gas of ultracold ground state molecules with a lifetime of several seconds. Utilizing double-microwave dressing, we achieved an extreme suppression of inelastic two- and three-body losses by factors of more than 10,000 and 1000, respectively. We found that losses remained suppressed across a wide range of dipole-dipole interactions, allowing the continuous tuning of the dipolar length from \u221221,000 to 12,000\n                    <jats:italic toggle=\"yes\">a<\/jats:italic>\n                    <jats:sub>0<\/jats:sub>\n                    , where\n                    <jats:italic toggle=\"yes\">a<\/jats:italic>\n                    <jats:sub>0<\/jats:sub>\n                    is the Bohr radius.
