Hey there!
Just wondering if you found a solution as I just encountered the same issue.
In my case, I found that it was caused by 2 frameworks I had recently added which were, by default, added with the "Embed & Sign" option, but they needed to be "Do not Embed". After switching that option for them the app installed.
Hope it helps anyone who might run into the same issue!
