2. Previous use of drugs targeting KRAS G12V mutations, including previous participation in cell therapy with similar targets Cellular testing and small molecule inhibitors targeting KRAS G12V mutations, etc.;
3. Allergic reactions are known to occur to any ingredient (such as dimethyl sulfoxide, cyclophosphamide, fludarabine) or structurally similar compounds treated in this trial;
4. Failure to recover from adverse reactions related to previous surgery or treatment to \< Grade 2 CTCAEV5.0;
5.
