Edit failed because of a diff timeout

Bug Reports

Describe the Bug

The parameter
“diffEditor.maxComputationTime”: 60000
does not prevent the diff execution timeout from occurring.
I am attaching a screenshot.
I have tried setting other parameters as well, but it still doesn’t work.
And in the latest version 1.3.8, the popup window that used to allow removing the timeout restrictions, which was present in version 1.2.7, no longer appears.

Steps to Reproduce

Do anything with big existing file

Expected Behavior

diffEditor.maxComputationTime
