Hi,
Try unchecking aggregation options one by one to see which is causing the issue.
This problem is quite common when aggregating as aggregation means all scripts or styles are combined within one file to reduce the number of requests.
In the process of merging all in one file, some misplacements can cause wrong CSS precedence or script scoping issues.
That said, you can try a combination of different configurations. You can also try excluding some js or css from aggregating.
