So we are on the same lines what exactly isn't working that you would like me to investigate.
From the looks of it UART comms is not working and timer interrupts are also not working? Is this correct?
Yes !! Collect.
Just been through the chip definition and both Timer0 and Timer1 look ok.
It is not working.
I've also been through the UART CAL comparing the register setup with a known working device and this also checks out.
So I'll wait for you to confirm the specific issue you've experienced.
I tried UART changed pin number. But that is not working.
I don't know how change UART CAL.
In your project you have all AltTx and AltRx properties set to Yes, what happens if you set these to No.
Looks same problem.
