The behavior you describe is common for Samsung card.
Of course, it could be a service or file system that locks up you shutdown. However, the fastest test to discard the media is to use the SD card copier to make a clone on another media, as it will take your existing system, format and "defrag" (even if the concept doesn't exist for flash storage), and give you a perfect comparaison. If you have the same issue on the clone, you know it's your system installation. If not, it's the media.
My card is running most of the time at 75-80 degree. This does not seem to create the issue. Heat would impact writing capacity and would make your card read only after being very slow to write. If you install btop, you can see the Io write graph to your card, and see if it's continuing long after a write operation. If a 1 GB copy takes 5-10 minutes to finish with this graph, then your card will soon become read only. You can also try a 1gb copy, and type "sync" when finished. It should be near instantaneous if your card is OK.
The qce parameter is a special kernel the team released to get extra speed from u2 microsd. It doesn't work with Samsung.
The fastest way to resolve you issue is to do the clone. Then you will know if you have to debug the system side if it doesn't work.
