Hi,
the Peripherals tool now incorrectly migrates to the configuration component that is intended for the UART driver 2.1.5 on this processor. We have reproduced the problem and our developers are preparing the fix.
For now, as a workaround, to generate code matching the driver 2.1.4 it's necessary to revert to older version of the component in your configuration by either using the archived .mex file if you have it or I have fixed the .mex file to use the 2.1.4 component and attach it to this post so you can use it.
Then, to avoid the incorrect migration next time check the 'ignore' checkbox in the Migration dialog when you are asked for this component:

We apologize for the inconvenience. The issue will be fixed, however only in the latest config tools version which is in MCUXPresso IDE 11.7.0 and standalone MCUXPresso Config Tools V13. I recommend upgrading to these versions.
best regards
