Critical error after WP upgrade in Jan 2024 and even after deactivating plugin

My website https://anderbaher.in has Dokan Lite and Dokan pro plugins installed since before Jan 2024. Both were working fine.

However, in Jan 2024, a WP update happened and since then Dokan pro started failing. I deactivated the plugin using myPHPAdmin and it worked till today.

I was trying to reinstall Dokan Pro today as I have paid for it for a year and need to use it on my website, but it again started giving issues so I removed both the Dokan plugins from the active plugin list in wp_options table. But the website is still down. No recovery email has come.

This is the error I get from an old recovery email …

When seeking help with this issue, you may be asked for some of the following information:
WordPress version 6.4.3
Active theme: shoptimizer-anderbaher (version 0.1)
Current plugin: Dokan Pro (version 3.9.7)
PHP version 7.4.33
