This question is worded terribly, but its premise is valid. Let me rephrase it:
If the Russians continue with their current strategy, is there a danger of a Ukrainian defensive line collapse?
The answer is a clear “no”, for the following reasons:
Russia’s current tactics are to attack with small infantry groups (maximum 30 soldiers) and without heavy armor (Main Battle Tanks and Infantry Fighting Vehicles). They aim to lose as few soldiers and vehicles as possible.
Furthermore, Russia conducts these attacks in many places on the frontline. They want to exhaust the already undermanned and overstretched Ukrainian defensive lines.
Due to Ukraine’s lack of infantry troops, locations seized by the Russians sometimes can not be counter-attacked.
As a result, the Russians momentarily gain one or two small villages every week and a few hundred square meters of ground. This doesn't seem much but it's more than what they achieved only two months ago (leaving their attack to the north of Kharkiv aside which was a total disaster for them).

With the current pace of their advance, the Russians would reach Kyiv in around 1,000 months. Short: there is no immediate danger to Ukraine's capital.
In addition, I don't see how the Russians could change their tactics to speed up their operations. They lack almost everything an army needs to conduct a successful big-scale operation: well-trained soldiers, air superiority, good logistics, and capable commanders.
The only thing they have in their favor is artillery superiority but this is only regarding the quantity (of artillery pieces and ammunition) and not the quality (i.e. their accuracy and longevity).
Last but not least, the more the eastern and southern frontlines retreat towards central Ukraine, the shorter the frontline (which will favor the defenders) and the longer the logistics routes for the attacker.
We have witnessed many times that the further away the Russians are from their logistic hubs in the Russian Federation, the worse their combat performance.
Should the Russians approach Kyiv once again, their troops will probably meet the same fate as last time: an utter and complete defeat.
