Version Compatibility Issue

I am using HDL_2019_R1 reference design(Linux 2019_R1)  with Vivado18.3 on ADRV9364-7020 RF SOM. I am able to configure the RF SOM but IIO crashes everytime I try to see the spectrum. When I am using HDL_2918_R2 reference design(Linux 2018_R2) with Vivado18.2 on same board everthing is woking well. Is this error because of compatibility issue or something else?
