Cannot create or rename entries in Explorer on a large repo

[daprahamian]

• VS Code Version: 1.55.2
• OS Version: macOS Big Sur 11.2

Steps to Reproduce:

1. Open a git repo with a large number of files ( > 500,000)
2. In the Explorer, create a new file
3. Wait up to 10 seconds

Expected: The file name entry should continue to exist until file name is entered
Observed: The file name entry is randomly terminated, resulting in either no file (if file entry was empty) or a partially-named file (if mid-typing)

This might be a duplicate of #114573, but as pointed out on that issue, I am still seeing this problem even though the previous issue is closed.

Does this issue occur when all extensions are disabled?: Yes

Dup of #112293

I also updated to my version of VS Code today and now am seeing this issue. I don't know the cut-off, but this is only happening on a very large repo, and not in any of the smaller microservice repos I contribute to. Including node_modules it's ~175k files
