The column `Condition` doesn't exist. Even though I can see the column is there!

It's not possible to give an exact answer without a reprex (See the (FAQ: What's a reproducible example (`reprex`) and how do I do one?).

To troubleshoot this, my recommendation is to start simply and to build to the more complex. The help page for rstatix::anova_test has a good starting point

library(dplyr)
library(rstatix)
#> 
#> Attaching package: 'rstatix'
#> The following object is masked from 'package:stats':
#> 
#>     filter
data("ToothGrowth")
df <- ToothGrowth
df %>% anova_test(len ~ dose)
#> Coefficient covariances computed by hccm()
#> ANOVA Table (type II tests)
#> 
#>   Effect DFn DFd       F        p p<.05   ges
#> 1   dose   1  58 105.065 1.23e-14     * 0.644

So, begin with

Dataovershootwithout means %>% anova_test(Condition ~ Distanceditalboundery) -> ANOVAtest

and start adding features from there.
