Part of the danger in the covid vax was due to the choice to use the spike protein. This made the non-mRNA vaxes dangerous too. But there were still mRNA specific dangers, one of them being the use of lipid nanoparticles to package the mRNA. I am not sure what heat will do to them. One concern is that an ingredient has a way to get into the ovaries, but not a way to exit them. Manufacturing the mRNA in a rush caused them to include incomplete mRNA sequences, which can instruct the cells to do unknown things. While cooking will destroy the mRNA, the things that the mRNA made may still be around and may cause issues.
