Hello Parshva,
Thank you for your response.
Please go to WooCommerce > Status > Logs > check today’s logs https://prnt.sc/vtxOCus25wtq , you need to increase memory one more time.
As a rule, so much memory is not needed, there is something on your site that uses it.
We would recommend you contact the hosting provider and:
1/ Increase memory limit
2/Ask for information about what exactly and how much uses the memory
3/Downgrade PHP version to 8.0
Kind Regards,
8theme team
