Getting Lost Connection on a Specific Query

Question

I'm getting a 2013 Lost Connection to MySQL server During Query on MySQL hosted on an AWS instance. The query below is the only one that causes this error (other queries run fine), and this query also runs with no issues on my Synology Docker container running MySQL. The only unique thing I have identified is that this query uses a CTE and the others that run successfully do not. The AWS MySQL is 8.0.23 and the NAS Docker MySQL is 8.0.28. I have checked the first things such as max connections, timeouts, etc and the values in use for the AWS instance are the same or higher than the settings on the NAS Docker instance. I have also tried a smaller data table and reorganizing the data table to weed out the possibility of data corruption. I have been searching for a couple of days and have not been able to find any hints on what the issue is. Does anyone here have any suggestions about where I should look next? Thanks!

SOLVED: I went ahead and updated the version on the AWS instance to the same version as the NAS (8.0.28) and the query runs correctly now.
