Hello, I have been using my x-t4 for about a year, and suddenly every time I am recording I get a "write error" after 5-20 s, and when trying to view videos I get a "read error", the same thing happens using both SD card slots and trying different SD-cards, all U3 cards that have been working perfectly previously. Taking and viewing photos still works as usual. Anyone who has had a similar problem or have any ideas on how to fix it?
