My wordpress site memory exhausted more than 1GB trying to debug with default

My wordpress site memory is exhausted

[02-Nov-2022 08:41:33 UTC] PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 262144 bytes) in /home/ahzabcollections/public_html/wp-includes/class-wp-query.php on line 3726

So, After too much debugging and all that i diagnosed that my theme is crashing and when i disable theme i can easily access wp-admin otherwise i am unable to login. I think it’s somekind of stuck in some loop.

Is there any way i can get call stack or trace that which function of theme is culprit and how to debug this properly in php way like stack trace.

Thanks in advance for any kind of help.
