It was a compulsory strike-off, most likely due to her failure to file accounts for any of the financial years after 2018-2019. So not due to a lack of cashos.
The compulsory strike-off initiated in December 2021 was suspended in January 2022 due to an objection being received - most likely from HMRC as there were likely no other parties eligible to object (no employees to speak of, unlikely to be any creditors, and no shareholders other than Guest).
I assume Guest then had to do some sort of deal with HMRC before the company was then struck-off.
