Hi, have u solve this problem?i meet the same problem too

[tachsin]

not quite sure but I think I tried different CUDA versions and it solved the problem

[AriadneZhao]

I think there may be somethong wrong with my code. i run examples and it works.

I can reproduce this error on mumax3.10 (Windows) with an input script from the mailing list. It seemingly does not occur on mumax3.11 anymore, nor on mumax3.10 built with Go 1.22. Perhaps this issue occurs with mumax³ compiled with older Go versions?
