RDS "Failed to start" when i changed the parameter group

with the default parameter group, there is no problem to pause and start RDS

but with the custom parameter group, i face "Failed to start" error everytime i pause and start RDS

after the "Failed to start" error, RDS backup and reboot the database automatically, and it works fine at the end.

• i've changed the parameter group from "default.mysql8.0" to the custom parameter group
• i haven't changed any parameters of the new parameter group, every parameters is same with the default parameter group

this is the log of the lastest pause and start,

i have no idea what is the problem, thanks for the any advice
