I’ve had my fair issues with large code bases too. I used doom emacs as well but had some time a couple of month so I configured emacs from scratch. Together with that I switched to lsp-bridge. I had some issues myself. Some of them I could fix myself and push upstream others I had to fix alongside the developers. Although most of the devs working on the lsp-bridge repo I have interacted with aren’t native English speakers or aren’t perfectly fluent in it, helped me with all the problems I had until now. I surges you give lsp-bridge another try and open issues for the problems you have.

Even better to know is that Sonoma can mess up apples integrated bootloader and leave you stranded unable to boot into your Mac. If anyone is interested there are some threads about it on r/AsahiLinux.
