I think its more likely that Diora is a b-tier actress at best(more c-tier imo) and she is in a field where past the age of 40 women do not get many roles outside of "Generic mom #34".
SAG strike only covers promoting and screen acting in film/TV projects produced by the studios I mentioned. WWE, music videos, voice acting, game shows, OnlyFans etc. are not a part of the strike. In fact, you can make and promote movies if they aren't major studio releases, like A24 or Lionsgate.
