It works well when editing, but there are two lines in one of the scripts that only work in editor and not in build. To fix: wrap lines 34 and 63 in LightProbeGroupControl.cs with #if(UNITY_EDITOR) and it should stop the errors.

Really Nice Asset You Do Have to Change Some Code in It to Make It Work but Besides That Has Saved 100+ Hours of Placing Probes 4/5 Because You Have to Modify It to Make It Build

It's free, and it works decently, however, it still leaves you with a fair bit of manual management work, and working with probes in general on any scale beyond 10 probes is just obnoxious. That said, theres better tools (though, paid) for handling 'all' the management of probes. Still, decent. And free.

As described, this is a simple way of quickly setting up a probe grid in your scene. It works perfectly all the way until you have to build, at which point you'll get errors as noted in other reviews here. I found Goteki45's solution to work the best for me (using #if/#endif statements to isolate the part(s) of the code which cause the build errors) to alleviate this issue. All in all, I'm saving a lot of time thanks to this asset, and thanks to the help of other helpful reviewers!

Remove from your project after using it

It is for free and does its job 100% better than my paid solution. And it works with Unity 2021 LTS. Just don't forget to fix the LighProbeGroupControl as stated in the comments below. I recommend the #if UNITY_EDITOR TheProblematicPieceOfCode #endifsolution. You just place this around the code that breaks the build process and then you don't have to delete the components and it works like a charm!

If you want a quick way to do a grid of lightprobes. This is the asset to do it.

This works when generating everything, but needs to be deleted after generating everything or it'll cause build errors. one of the reviews shows how to fix this.

Congratulations to the creator!
