This is a processor malfunction. You can switch the sd card operation in the bios, install drivers from other tablets, but these are all temporary solutions.

SD cards over 64GB officially is not supported.
To use exFat / NTFS in android you need to get root and install patch chuwi-android-fs-1.0.4-install.zip - Google Drive
