[Solved] NextDNS segmentation fault

Hey guys, hope you can help...
I'm using stable OpenWRT 21.02, when I try to install nextdns package
it failed and show this error.

Package nextdns (1.37.1-1) installed in root is up to date.
Configuring nextdns.
Segmentation fault
Collected errors:
 * pkg_run_script: package "nextdns" postinst script returned status 139.
 * opkg_configure: nextdns.postinst returned 139. 

How to resolve this ?
