What system were you using on your Intel Mac? If it was earlier than Catalina then some of the scan components may be 32 bit and won't work with any system newer than Mojave. You can see by downloading and using the free GO64 app to see which apps have 32 bit components and limiting their usability.
If all else fails try the demo version of VueScan. It allowed me to use a very old Canon scanner with Catalina and later. I prefer VueScan over the software that came with my new scanners.
You can get VueScan with a one time purchase with no updates (which is OK as it only updates when new scanners are added). If you get a new scanner that isn't covered you may have to purchase again.
