With the latest XCode 11.4.1, we have an issue running the UI Tests. The method that is failing is connected to reading the cells from a table view:

    func count() -> Int {
        let table = app.tables.firstMatch

        return table.children(matching: .cell).count
    }

The error that is shown after a couple of seconds is:

Failed to get matching snapshots: Timed out while evaluating UI query.

The same error is received if I won't enumerate the table view cells in order to click every one of them:

table.cells.allElementsBoundByIndex

I saw the release notes for XCode 11.4 and tried to set up executionTimeAllowance but didn't change anything.

I am also experience the same.
Failed to get matching snapshots: Unable to perform work on main run loop, process main thread busy for 2.0s - recommend retry by client
But working fine in Xcode 11.3.1
