Assertion error starting Phy2 for KS3 data

[HiroyukiKato7]

I'm not sure if this is related to #329, but I get an assertion error starting Phy2 for KS3 data. The same recording data sorted with KS2 has no problem. In case of #329, it seems that Phy2 at least opened, but in my case the Phy2 window does not even open. The error message is as follows:

←[31m17:08:41.799 [E] init:62 An error has occurred (AssertionError):

I would appreciate it if I could get help in resolving this issue.

Thanks

It seems that this happens when I exclude some channels for sorting. I can open Phy when I use the whole 64 channels. (This is from Cambridge 64-ch linear probe recording)

hi,
similar problem here using phy2 to load data produced by kilosort3 (updated on sept 03, 2021). I didn't have the problem before.
