New install on mac, ctrlp does not show any files

[ThomasChaffey]

Fresh install on OS X, using Vim version 8.2 and VimPlug.

Pressing (or entering :CtrlP) brings up the CntrlP menu as expected. However, the plugin doesn't return any entries, even if I type in a file name which I know is there.

I've attached my (slightly messy) vimrc. Happy to help with further debugging, just let me know what you need.

Further update: I have an identical setup on another Mac. The first time I start CtrlP in a vim session, the following error flashes for a second or two, then disappears:

Error detected while processing function ctrlp#print[31]..<SNR>143_setlines_post[6]..ctrlp#files[8]..<SNR>143_GlobPath:

Further update: this seems to essentially be the same bug as #540

Running CtrlP: <home dir> works as expected, running in my project directory does not. My project directory has spaces in the file name.
