nightly crashing due to "brave_stats::BraveStatsUpdater::BuildStatsEndpoint"

Description

Nightly is currently crashing every few seconds after startup or after a few minutes. I have a brand new profile that crashes every ~5min but I also have a profile that crashes every ~1-2 seconds after startup making it almost impossible to use.

We’re also getting several reports from the community as per the following:

• https://github.com/brave/brave-browser/issues/13856
• https://github.com/brave/brave-browser/issues/13844
• https://github.com/brave/brave-browser/issues/13842

@bsclifton also ran into the above issue on his machine and reported the crash via #crashes in Slack.

Steps to Reproduce

1. launch 1.21.35 CR: 88.0.4324.96
2. login into a few websites (GH/Gmail in my case) and wait ~10min or so
3. eventually Nightly will crash

I have a profile saved that basically crashes after startup as well so it makes it impossible to use Brave on Nightly.

Actual result:

Nightly crashing pretty often which makes it impossible to use

Expected result:

Nightly shouldn’t be crashing.

Reproduces how often:

So far I’ve managed to reproduce the crash on three different clean profiles after ~20min of usage.

The latest Version 1.19.92 Chromium: 88.0.4324.152 (Official Build) (64-bit), seems to have fixed the tab crashing error for me. Version 1.19.88 was the only errored version it seems in the release versions.

We also released https://github.com/brave/brave-browser/releases/tag/v1.21.36 that had a quick fix as per https://github.com/brave/brave-core/pull/7753. That should have resolved the issue 👍 We’re also working on a longer term solution as per https://github.com/brave/brave-core/pull/7754. We’ll adjust our process so this doesn’t happen.
