Wok Weirdness

There was something weird about my wok last night. Instead of being oily on the surface as per usual, it had some sort of coating that was extremely hard to remove. I had to get out some bar keepers friend and scrub it a lot. I think it might be because it sat out for a long time since my last use. Do you think it’s alright to still use. Any thoughts would help. Thanks.
Usually I just let stuff burn onto my wok, well, the one I use to have.

It had to be seasoned so I just let it sit on high heat. After use I just cleaned it by running water around the pan while it was still hot to rinse it out and that’s it.
