Star gooseberry trees leaves adversely affecting growth of other plants

In July August 2021, the star gooseberry tree near the domain investors mailing address was cut , so the leaves stopped falling in the compound
The domain investor threw some seeds in the area, and a large number of papaya plants started growing rapidly.
After a year, the star gooseberry tree is again growing and the leaves again started falling in the compound.
This has adversely affected the growth of the papaya plants,.they are shedding almost all their leaves and no new plants are growing.
