I found a strange solution for now, I installed ue5.0.3 then took the shadercompileworker.exe file from binaries folder and replace it into the ue5.1.1 folder.
From the start the software gives a lot of errors but then it starts compile the shaders.
I am not sure but this works at this moment and I can use my projects.
Yes all the next projects openings are working well and without any issues.
I have found also one thing, after I updated my CPU to 13900k and it is very hot so I made undervolt in bios. Then I updated UE to 5.1.1 and got this issue with shadercompileworker, so I tried one thing and reset undervolt and after that I don’t have this issue in UE. I really have know idea how this is depend on but now all works well
I may not have noticed such a problem before, but today I ran into it.
At first, I couldn’t open UE 5.1 and 5.6, then by disabling MSI Afterburner, I was still able to open the engine before opening projects or creating a new one. I was able to log into the old 5.6 projects with RTX enabled, but when I tried to create a new project without RTX, this error started appearing during compilation. I tried to update the drivers, delete the cache and other data of the unreal engine and epic launcher.
After these actions and restarting the PC, I was able to open the engine and old RTX projects without disabling MSI Afterburner, it didn’t bother me anymore.
In the end, only creating a project with RTX enabled helped, everything compiled fine and worked.
I don’t really need to work in UE5 without RTX enabled, but the situation is strange, it used to work, but now there are problems.
It seems that after the recent upgrade of the PC, namely the motherboard, processor and RAM, I have never opened projects without RTX, perhaps this has something to do with the transition to DDR5, since DDR4 - 3200 and the I9-9900K processor used to be used.
Right now my PC is: I9-14900K, RTX 4070 Ti Super, DDR5 6400 XMP, NVMe SSD
