Appears to be protest voters rather than die hard communists.

Sounds like she is not clear on what she wants. On the one hand a full on communist praising Hugo Chavez yet on the other her response to COVID-19 was very individualistic, capitalist orientated even.

According to Wikipedia (agree not the most credible source)

“Regarding the COVID-19 pandemic, Wagenknecht has opined that only the elderly and vulnerable groups need to be vaccinated against the disease, and agitated against the German government response to the COVID-19 pandemic. Wagenknecht has opposed proposals for COVID-19 vaccine mandates, arguing they should be a personal choice.

Wagenknecht's positions have been compared to those of the far-right Alternative for Germany. In November 2021, party colleagues such as Maximilian Becker, Martina Renner, and Niema Movassat suggested that Wagenknecht leave the party.”

Perhaps she just always takes the opposing view to any argument.
