UART4 RX not working using Interrupt or DMA mode

I am using custom designed board having STM32H745BIT6 and 25MHz external crystal with LDO Only as Power Selection from RCC settings.

I am trying to check UART4 with pins PC10 and PC11 and flow control disabled.

So Transmission is working well using Polling and Interrupt mode but reception is not working when using Interrupt or DMA mode. Reception is working in Polling mode.

Attaching .ioc file for reference.

Please check and suggest a way to resolve this issue.
