Unreal Engine freeze when Saving

Thanks for the logs! So most of the logs don’t have much relevant information besides the blender plugin is struggling a it but that’s not likely your issue. If you take a look in the logs, 2 of them show a crash context GUID like this: UECC-Windows-2E12A0984471EB1CD1EA2EBA0CB59A63 if you check your ProjectFolder->Saved->Crashes you should find a corresponding folder with an XML crash context (mostly useless but sometimes has good hints) and another log file that might have what we’re looking for. Could I get a look at both of those for the 2nd log you sent? (GUID: UECC-Windows-2E12A0984471EB1CD1EA2EBA0CB59A63)
