Error using gpuArray/eig; EIG did not converge at index 84321

Hi,

I am trying to use kilosort 2.0 on my data but it I get an error during optimisation of templates -

Error using gpuArray/eig
EIG did not converge at index = 84321.

Error in svdecon (line 23)
[U,D] = eig(C);
^^^^^^
Error in learnAndSolve8b (line 411)
[A, B, C] = svdecon(UA);
^^^^^^^^^^^
Error in main_kilosort (line 75)
rez = learnAndSolve8b(rez);

This happens while optimising the templates. In one such cluster, the C matrix returns NaN and kilosort crashes. I tried changing the ops.Nfilt to a lower value instead of default 1024, thinking it could be a memory issue but it's not.

I thought it could be an issue with channel map but when I separately check the data in the GUI, it seems alright.

Has anyone else faced this issue ever ?

Looking forward to hearing back. Thank you !
