Error when adding a new post

I’ve deactivated and reactivated plugins… tried reverting to an older theme version but nothing is helping. When I try to ‘add a new post’ I’m getting this error:

TypeError: (0 , nt.__experimentalGetShadowClassesAndStyles) is not a function

If you just updated to WordPress 6.5, try doing hard cache clear in browser. We had jquery error when trying to set a shedule date, clicking on the date nothing would happen, so could not schedule anything. Took us a while to note something changed with jquery and java in latest WP.

a) in Chrome hit shift + F5 to reload admin page without cached JS files
b) do “save permalinks” in main WP settings to clear some transients

Not theme related as far as java weirdness we were getting. Might not apply to your issue.
