MAX10 set_false_path failure

In the timing analyzer, there is a report mention about ignored constraint. You can double click it to see your constraint take effect there.

Looking into your constrain set_false_path -from [get_clocks *] -to [get_registers {CDC_2FF:inst14|ff1}]

This will be incorrect because you cannot set the * there to get clocks. I

My suggestion is to get the register that you want to false path.

set_false_path -from [get_registers <register name>] -to [get_registers {CDC_2FF:inst14|ff1}]

We do not use false path from clock to register.

either way, you can use set_clock_groups, this will false path the clock in two directions
