kable() results not displaying below RMarkdown chunk

Hi,

When I run the chunk below, the results appear only for seconds. The table then desappears, leaving only the window. In a new window the problem remains.

```{r, echo=FALSE, message=F, warning=F, include=T}
# tabela resumo dos modelos univariados

total_univ <- rbind(reg_univ1, reg_univ2)
colnames(total_univ)=c("Coeficiente","OR","IC OR 2.5%","IC OR 95%","Valor-p")
kable(total_univ, align="l") %>%
  kable_styling(full_width = F)
```

Does anyone know the possible cause and how to resolve?

Thanks!
