Network error: Unexpected token

After WordPress auto-updated to the latest version, the endpoint
/wp-json/jwt-auth/v1/token
stopped working and now returns:

{ "code": "rest_no_route", "message": "No route was found matching the URL and request method.", "data": { "status": 404 } }

What I’ve already tried:

• The plugin is installed and activated.
• .htaccess is default and supports permalinks.
• /wp-json/ is accessible, and other REST API routes are working fine.
• Tried switching to a default theme and disabling all other plugins — no effect.
• Tried from incognito mode and another browser — same result.
• Reinstalling the plugin did not help.
• The issue only appeared after the WordPress core auto-updated.
• Logging into the WP admin works fine, users exist and are active.

Is there any known conflict with the latest WP release?
How can I restore the /jwt-auth/v1/token route?

Any help would be appreciated 🙏
