Allowed memory size exhausted / Incompatibility

I am attempting to use this plugin along with All Products for Woocommerce Subscriptions however I receive a memory exhausted error when both are enabled while trying to add an item to the cart. I suspect that there is an infinite loop happening and I was curious if you may have any information or recommendations on how to fix this issue?

I am also reaching out to that plugin developer to see if there are any useful filters that I can utilize to skip over any force-sell products but I thought I would ask here as well.

When I deactivate the other plugin, the cart works as expected. While the other plugin is enabled, I always receive the same memory exhausted error, and increasing the memory did not help. Interestingly, the number of bytes trying to be allocated is always the same, 20480.
