As you can see below, my new Lenovo laptop has essentially the same problem as the others who have posted here. Seti works fine but Collatz tasks crash immediately. My driver version is 21.20.16.4590 and it is using OpenCL: 2.01. I have an older laptop with an Intel GPU using OpenCL: 1.02 and it does Collatz tasks with no problems. Could OpenCL: 2.01 be the problem here?

OpenCL is not loading properly with your current driver. I would look for newer one or maybe go back a version. OpenCL is a pain with Intel and the DLL Reg pointers fail often.

Not a viable option for this new computer. The current driver is the latest and there is nothing in "rollback".

Besides, since SETI is working fine, I am more inclined to believe it is a Collatz problem with OpenCL 2.01/Intel 6.XX drivers. And, apparently, you thought that, too, at one time (in Message 24114).
If not Collatz may just not be ready with Intel 6.XX drivers.

Problem solved! I used DDU to uninstall my Intel driver (in Safe Mode). Then reinstalled the same driver. I now have a Collatz WU that is running normally and should probably finish later today.

Note: Before originally posting about this problem, I had deleted and reinstalled the Intel driver - without using DDU. Obviously, there was some junk in the driver space that was causing the problem. The first reinstall didn't clear it but DDU did the job.

Looks like Collatz doesn't have a problem after all.

I would try then UNINSTALL of the BOINC software and install the latest version as others have had issues also with the newer Intel GEN of processors.

Already running latest BOINC software - version 7.8.3 (x64).
