Greetings!
It is difficult to provide you the causes of the errors by seeing the code as it could be because of the components you used or the SOQL queries which are returning huge records.
So,I would suggest you to go through the below document (https://help.salesforce.com/articleView?id=000323828&type=1&mode=1) for the causes and how to troubleshoot the issue.
You need to enable developer Mode to check which components are using the high view.
Reference:https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_tools_edit_toolbar.htm
Kindly mark it as best answer if it helps so that it can help others in the future.
Warm Regards,
