No, the Canon EOS R50 is not compatible with the Nextorage NX-A2PRO 160GB CFexpress Type A.
Canon R50 has a single SD UHS-I slot — no CFexpress slot. CFexpress Type A cannot be used on this body. Per Canon's own manual, the R50 supports SD/SDHC/SDXC UHS-I cards only, with no CFexpress interface at all.
