Hello everybody!
I have a problem with my EOS M100 and my Lexar 16GB SDHC. I have always used this SDHC and it has always worked. Now I downloaded the photos on my mac and I deleted everything on the SDHC. When I put the SDHC back in the camera it did not work anymore, saying "memory card error". The card is not on locked position and unfortunately I cannot format the SDHC card from the camera itself because the option "format" is grayed out in the menu.
Any idea why this happened?
Thank you everybody

Sounds like a memory card failure and time to try a new one. Be sure to only use the full size memory cards, not the micro-SD cards that require a plastic adapter in order to use it in the camera.

Did you format the card in the Mac, to the Mac format type? The camera can't read that.
Can you format the card in the computer to FAT/FAT32 format? Or format it on somebody's Windows or Linux computer to FAT/FAT32?

As Norman said, the Mac format is not compatible with the camera format. If you cannot find a windows computer, try to see if the Mac will format the card in FAT32 format. If you can get the card to FAT32, then format the card in the camera.
Formatting the card, rather then deleting all the files is definitely the way to go. However you should not format the card on any other device than the camera to avoid any incompatibility issues.

Hidden files placed on a memory card by Finder will sometimes confuse a camera.
It the card has not failed, https://support.apple.com/guide/disk-utility/file-system-formats-dsku19ed921c/22..6/mac/14.0
macOS calls the formats ms-DOS and ExFat depending upon amount of storage. Formatting to ms-DOS on the mac might enable camera to format the card to its preferred format. https://support.apple.com/guide/disk-utility/erase-and-reformat-a-storage-device-dskutl14079/mac
I always move the switch on the memory card to write protect before putting it in the card reader on my iMac. Then I erase the card in the camera with the format menu option after all of the photos are stored and backed up.
If the card has failed, it is time to buy a new card. Lexar has refunded to me the cost of a failed card in the past.

Sorry guys. You have ALL over thought the problem. Just like in the Movie Sling Blade when the man brought his mower to the repair shop because it wouldn't start, the first thing the Karl did was discover it was out of gas.

Sorry guy, the OP clearly said the card was UNLOCKED. So we don't really know what the story WAS.
Anyway, it was 1-1/2 years ago, so who cares anymore?

Perhaps beware of the pitfalls of not reading all of the information in the OP's post and then making a definitive statement that is dismissive of others' attempts to resolve the situation. Even if you missed it, you put yourself in a much less vulnerable position by posing your thoughts as a question rather than making dismissive statements of those who are trying to help.
