Experienced the same since Polylang 3.2.2.
Found this issue:

• Oxygen Builder calls template preview with added parameters, like
  https://domain/mycategory/?action=ct_render_shortcode
  and expects a JSON response.
• Polylang detects “mycategory” to be a category name, redirects to https://domain/mycategory/ (without parameters) and returns HTML.
• Oxygen Builder throws an error “Unexpected token < in JSON”

I wrote a Code Snippet to “fix” this temporarily:

add_filter('pll_check_canonical_url',function($redirect_url, $language){
	// $redirect_url is the canonical URL evaluated by Polylang for this request
	// e.g. https://domain/projects/

	$requested_url = pll_get_requested_url();
	// initially $requested_url might differ since Oxygen adds URL parameters
	// e.g. https://domain/projects/?action=ct_render_shortcode

	// if $requested_url doesn't match $redirect_url
	if ($requested_url != $redirect_url) {
		// get the $requested_url without any URL parameters		
		$requested_url_no_params = preg_replace('/\?.*$/','',$requested_url);
		// if $requested_url_no_params now matches $redirect_url
		if ($redirect_url == $requested_url_no_params) {
			// return the initial $requested_url with parameters as the desired $redirect_url
			$redirect_url = $requested_url;
			// since now $requested_url and $redirect_url match, Polylang will not attempt to do a redirect.
		}
	}

	return $redirect_url;
},10,2);

Solved the issue for my use case.
Tested with WP 6.0, Oxygen 3.9, Polylang 3.2.2 and 3.2.3.
Test and use the temporary “fix” at your own risk.
