Hey there @Galislorer! Welcome back to the community! It looks like you’re having lots of material errors. Some materials are invalid due to different reasons it seems.

For this specific material, it seems like it’s on a nanite mesh, which doesn’t yet support translucency. (This shouldn’t crash you but it’s good to correct this by either changing it from Nanite or changing the blend type).

Warning: Invalid material [MI_MS_Glass_Material_Inst2] used on Nanite static mesh [SM_pannello_trasp]. Only opaque or masked blend modes are currently supported, [BLEND_Translucent] blend mode was specified.

For example other errors show materials are missing nodes or having errors on certain nodes:

The first thing to do is go through and correct as many of these as possible, this may solve your issue outright.

Looking at the GPU breadcrumb trail here, it shows the first operation that failed was translucency. Since you have lots of translucency material errors, we wanna clear them up before continuing. Any object with a translucent material for now should be reverted to standard SM or translucency dropped.

@SupportiveEntity Ty for reply me. I resolved all the warning from any glass material and i also disabled the settings :" Enable order indepedent Transparency (Exsperimental)" . This settings even i corrected the other warnings, continued to crash unreal when the option was checked
