Thanks for your input.

We were using 2022R2 and now switched back to 2022R1. Then, we haven't had the warning message.
However, we are having a divergence issue with our multiphase geometry. The mesh quality is almost perfect.
We are assuming that the divergence is caused by the multiphase mode because we removed gas phase from our model and ran it with the electrochemical package. It worked well. The new model (without gas phase) is working fine and there is no difference between the old one (multiphase) and the new one (only liquid) other than multiphase.

Can you give me advice for this? Please let me know if you need further information of our model
Thank you for your help.
