Reducing CRM (on premise) Database size that is too big

Hello,

I am looking for a way to reduce the size of the crm database which is too large.

Here is the size of the table in my crm database :

I have tried deleting attachments via bulk deletion but it failed due to sql timeout.

I tried through bulk data updater but also failed due to sql timeout.

then I have also tried deleting data in the AsyncOperationBase table following this guide,

support.microsoft.com/.../performance-is-slow-if-the-asyncoperationbase-table-becomes-too-large-in-microsoft-dynamics-crm-334a0738-e132-1ea7-cab3-7fd68cb823a4

the number of rows has been reduced by half, but the size remains the same.

Is there any way to avoid timeout during bulk delete or bulk update or any other way to reduce my crm db size?
