hap ax3 zerotier invalid identity loaded from disk

Hi. My setup: hAP ax^3, RouterOS 7.19.1, zerotier package 7.19.1.

Install zerotier package, reboot, go to Zerotier/Instance, enable zt1 instance and get status “failed”.
Enable logs for Zerotier and get this one every time when i try to enable instance:

zt1: /pckg/zerotier/zerotier-one/zerotier-one: fatal error: invalid identity loaded from disk. Please remove identity.public and identity.secret from /ram/zerotier/9 and try again

9 - is autoincremented number.

I don’t have access to /ram/zerotier, so i can’t see what’s wrong here. So what should i do to fix this?

I would first create a supout.rif file and file a support ticket so they can already look into it.

Next step would be to netinstall that device and see what happens then.
But I would not do that until you received feedback from support …
