Compiling Shader freeze my PC

[yontala]

Hello,

When I ty to launch some games the compiling shader screen froze and my PC didn't respond at all.
It only happens when I use D3D Backend and use Exclusive Ubershader
I search on the forum but I didn't really found some information about this incident.
Could someone help me or give me a link where I could find some information about this ?

thanks in advance.
