Testcafe fails on starting

[AlekseyKravtsov17]

What is your Scenario?

We have a set of tests which executes every 30 mins 24/7

What is the Current behavior?

We have around 50 executions per day, but approximately 30% of the executions fail randomly. The test code is exactly the same. We started to face this issue more frequently since February 26, 2025 10:52 GMT. Exactly after the update in Ubuntu 22.04 actions/runner-images@78d6387

Before this date the following issue occurred only 1-3 times per 1-3 weeks.

We hypothesized that it might be due to a chrome version update, and tried running the tests on the previous version, but they fail with the same frequency on both Google Chrome 133.0.6943.53 and 133.0.6943.126 versions

ERROR Cannot establish one or more browser connections.
1 of 2 browser connections have not been established:
- chrome:headless

Hints:
- Increase the Browser Initialization Timeout if its value is too low (currently: 2 minutes for all browsers). The timeout determines how long TestCafe waits for browsers to be ready.
- The error can also be caused by network issues or remote device failure. Make sure that your network connection is stable and you can reach the remote device.

Type "testcafe -h" for help.

The issue seems to be absolutely the same as it was there #8292
And according to the comments under this issue it still reproduces for many people.

Tests are running in GH hosted agents (runs-on: ubuntu-22.04) with concurrency 2. browserInitTimeout is already huge, no issue with app under test.

We also have similar configuration of executions with playwright, no similar issues there. So we don't think the reason in GH hosted agent.

What is the Expected behavior?

Should work as other ~45 executions

What is the public URL of the test page? (attach your complete example)
