Ubunutu 20.04 Gnome shell crashing on enabling Extensons from Gnome Tweak Tool

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
Gnome Tweaks Tools

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

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

I tried enabing them even through dconf editior but the same thing happens. The shell crashes immidiately.

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
