GNOME Shell crashing on enabling Extensons from GNOME Tweak Tool on Ubuntu 20.04

I recently upgraded from Ubuntu 18.04 to 20.04. Everything is working fine except the Extensions.

I tried enabling them using GNOME Tweaks Tool

Tweak tools -> Extensions Sidebar -> Top right corner

But as soon as I toggle that, the shell crashes and I see this screen.

I am forced to logout and then login again. And then extensions are disabled again.

I tried enabling them even through dconf Editior but the same thing happens. The shell crashes immediately.

I tried looking for solutions but it seems like the issue is experienced by extremely few people. I could only find one question for it on Reddit (no solutions on it yet).

Does anyone know what the issue is about and if there is a fix for it? I am not able to use extensions and this is really bothering me. I am ready to provide any further details necessary to fix this issue.

This is most likely due to incompatibility of some extension(s) with the current version. It seems as soon as you're enabling extensions, the incompatible extension(s) is/are causing the crash.

To fix it you remove all the extensions and then manually reinstall them one by one.
