ProBuilder - Can't Drag Select

Hello!

I’ve faced with the very strange issue recently.
I can’t drag select (vertexes/ faces/ edges), but the single selection is still working.

Unity version: 2020.1.4
ProBuilder version: 4.2.3

I’ve already tried to reset all settings, reimport probuilder, and reimport all the assets in my project.
And some times it helps for just couple of minutes and the suddenly the issue emerges again, and I can’t see any regularity in it.

My first thought was, may be this is because I’m using Custom SRP, but still can’t see the issue there.

May anybody point me into right direction to solve this? ProBuilder is very critical for me now and I’m up for any solutions just to make it work.

PS. There is no errors or warnings at console output.

Forgot to mention. I’ve also tried different ProBuilder versions started from 4.0.2. Some of them are not compatible with 2020.1.4, with others I’ve facing the same issue. So maybe it does have smth to do with the Custom SRP.

I am looking at this today, will report back as soon as I have an answer.

Ok, short answer is that fixing this properly is going to require some URP features that are not yet available. However I was able to find a workaround, so look for a fix in the next patch.
