Error in t.test of independent groups: data are esentially constant

I am getting this error when I performed t.test of independent groups created from terciles of several variables. It is strange because when I coded first time it worked, and suddenly has stopped working
I post a sample of my database where I am getting the error

The code need to be wrangled a little bit. Not sure what is happening but repeating what I said it is an error that has poped up out of nowhere

sample%>% 
dplyr::select(paciente, matches(c("_v00", "_v01", "_v66")) &  !matches("d_"))  %>%
  pivot_longer(-paciente) %>% 
  separate(name, into=c("name", "time"), sep="_v") %>%
  dplyr::filter(time == "00" | time == "66") %>% 
   mutate(time = factor(time)) %>% 
  pivot_wider(names_from=time, values_from=value) %>% 
  dplyr::select(-paciente) %>% 
  group_by(name) %>% 
  do(tidy(t.test(.$"00", .$"66")))

Error in if (stderr < 10 * .Machine$double.eps * max(abs(mx), abs(my))) stop("data are essentially constant") : valor ausente donde TRUE/FALSE es necesario

Thanks in advance

It comes from the -Inf in ln_geaf_tot_v66. The t-test doesn't seem to know what to do with an infinite value.
