LTCG exemption -6 month deadline

Hi,

I sold my house in Aug 21 which attracts LTCG, unfortunately I have missed the 6 month deadline to invest in bonds issued by the IRFC, NHAI, PFC, and REC. Questions below ..

1.Can investment in sovereign gold bonds (SGB) used for LTCG exemption under section 54EC ?

2.Is there a way I can invest in the bonds (IRFC, NHAI, PFC, and REC) now in July 22 and claim exemption ?
 

any other solutions most welcome.
