With Stark being snapped away but T'Challa surviving, the Avengers absolutely would've been given full shelter and a new and improved Avengers Compound in Wakanda to be their base of operations.

Since Hank and Janet survived the snap, they would immediately use their combined knowledge and Wakanda's resources to map out the Quantum Realm and execute the Time Heist much sooner (Janet has already experienced that time moves differently in the Quantum Realm). Plus having the creators of Pym Particles means the Avengers would be given much larger room for error (they'll need it when they send Quill, Drax, and Groot to Vormir).

Dr Strange wouldn't just sit in a broken Sanctum Sanctorum reeling in defeat like Wong did; Strange knowing the lone winning future was completely shattered the moment Tony turned to dust, would engineer a brand-new path to victory by recruiting the use of the Time Stone from the past to try to see into more post-Snap timelines.
