Text gets weirdly distorted / garbled when saving as PDF

Hi, I've been struggeling with this problem for some time now. Always when I want to save my PSD as PDF some strange things happen with the text. I usually just use the stock export presets. I can't really identify the cause, it happens quite randomly but also quite often. Sometimes the text will be like in the example image but sometimes certain text parts will just be upside down. I attached the export options. I use a MacBook Pro M1.
