ImageMagick 7.1.1-33 can’t handle the conversion

Plugin specific area in media settings of wp-admin shows the message “Control how .heic images are handled during uploads.”. Heic files get uploaded, but no type of control shows during uploads, so no web copies of the files are created. Original file is displayed as a gray square in media library. As specified in the title ImageMagick is at its 7.1.1-33 version. I’ve contacted the host support, but they told me they can’t manage to downgrade/upgrade the extension. Could you please help me?
