Hello,
There are 2 ways, you can set https://prnt.sc/2DZvuplWMv6A in Theme Options > WooCommerce > Shop elements > Quick view OR disable More Details Link https://prnt.sc/ck6O_XM-_oMQ
It is because the description contains tags, and when a part of the excerpt is taken to show in Quick View, some unclosed tags cause the problem.
Regards
