Are you referring to "enable concurrent DNS name resolution" option in the name
resolution preferences? I'm not aware of it ending with "error"

With concurrent DNS resolution turned on, the c-ares library does the DNS
lookups and may be doing it differently than the built in OS functions (for
example, something like contacting DNS servers directly instead of using a
local 'hosts' file first) whereas turning it off uses the normal operating
system DNS resolution routines.
Which version of Wireshark were you using before? We used to use the ADNS
library, but now we use c-ares for concurrent (asynchronous) DNS resolution.
This may be why the new version isn't working the same way.
