Session Deleted Because Of Page Crash Selenium

在docker上跑Selenium+ChromeDriver+Chrome无头模式报错： UnknownError: unknown error: session deleted because of page crash from tab crashed. Selenium.common.exceptions.WebDriverException' unknown error: session deleted because of page crash from unknown error: cannot determine loading status from tab crashed. となってしまいます。 chrome.logを見たところ、キャプチャを撮るところでエラーになっているようでした。. Tdu trainer 1.66 app. Session deleted because of page crash - regenerate. Node JS in Windows; appium automation test cases on multiple android d. Hoi4 portrait maker. Jenkins Master Slave August (7) May (3) April (1) March (3) February (1) January (4) 2014 (19) December (8).

Hello All,
Perhaps someone can help me figure out why the below is happening and fix it?
Given:
All the below are on Windows 10 / Server 2012 R2
Selenium .Net (C#) tests (Selenium.WebDriver nuget v3.141.0, .Net Framework v4.8)
ChromeDriver 78.0.3904.70
Google Chrome Version 78.0.3904.97 (Official Build) (64-bit)
Tests run automatically by Azure DevOps Server (installed on-prem)

When:
Seemingly randomly once every few hours (one out of every few dozens of tests runs)

Then:
ChromeDriver logs seem to show it freezing for ~70-90 seconds and then resuming. Please see log snippet quoted below.
Test-side (C#) driver class times out after 60 seconds of ChromeDriver inactivity and fails the test.
These 'freezes' occur at random times, in random parts of the test suite. Sometime following a ClickElement command, sometimes following a Navigate command. 
Please note:
The line where the freeze occurs seems to always be similar to this:

How can I further investigate what the cause of the 'freeze' is and fix it?Session Deleted Because Of Page Crash Selenium Webdriver
