I try another project with 42 submodules, when I use `Borg` to install
 `Corfu` extensions, I need to set two load-path on `.gitmodules`. And this
 setting will trigger the same issue.

```
[submodule "corfu"]
	load-path = .
	load-path = extensions
	path = lib/corfu
	url = git <at> github.com:minad/corfu.git
```
if I remove the load-path, just leave it as below, project.el wokrs
well.
```
[submodule "corfu"]
	path = lib/corfu
	url = git <at> github.com:minad/corfu.git
```

May be the above infomation can help you.

Thanks, I try to set project-vc-merge-submodules to nil, and It works.

By the way, I also tried `projectile` on the huge .emacs.d, It works but
can feel the latency.
