Thank you Alter Hase for your response and I am interested to learn where you got this information from, because it would technically be a change in the details of her application.
Basing it on this information, I would think that one should not apply for EUSS after one has formally applied for citizenship, as is the case for user
verty.
How long it takes
You’ll usually get a decision within 6 months - some applications can take longer.
If you have not already started a citizenship application, apply to the EU Settlement Scheme instead to continue living in the UK after 30 June 2021. You can apply for citizenship after you get settled status.

There is also this:
If you have settled status, you must apply for citizenship with this status instead of permanent residence status. Do not apply for citizenship with your permanent residence status if you have settled status. If you do, your application will be rejected.

Also, according to the website as well:
If your circumstances change
You should contact UK Visas and Immigration (part of the Home Office) if your situation changes during your application (for example, you move house, get married or are arrested).

I agree it doesn't cost anything to apply to the EUSS, but it is considered a change in status. I think the best thing would be to contact a lawyer or the CAB. A lot of immigration lawyers have consultations and you can ask for a reduced fee usually.
I don't want to scare you, but I would feel a lot better if the HO or an immigration lawyer was able to confirm this. Changes after an application often happen but generally, you should update HO on any changes, such as a conviction, birth of a child, but perhaps a change in your legal status.
I am happy to be wrong but it's a dangerous thing also to change a legal status and not update the authorities. My former AIRE got mad at me that at the time I renewed my passport to the time I had to go to the Consulato, I had moved and while it was minor, they informed me that any changes need to be updated immediately. This move was only three weeks before I went to collect my passport. I basically got a stern look and a theoretical slap on the wrist.
