Unusual Errors since upgrade to ue5.5.3

Has anyone else noticed unusual error when testing your projects? Recently, I have been seeing unusual things such as when starting a test, I log in a character and my inventory fills up with an Item different amounts each time. Yet, I have no code in my game that initializes items into my character’s inventory. 3075 items added 15 items added it’s a different amount each time and then at other times it doesn’t happen at all. Also, when duplicating a character to test a function some of the functions fail to work yet work on other duplicates which has other functions not working then suddenly everything works fine. this has start only recently after the add on of FAB. (BTW I HATE FAB!!! hence why I didn’t use FAB to start with before Epic added it on. Now I’m being forced to use it… UGH!)

How does UE5.5.3 add stuff to my inventory without any script to do that? Yes, I have an inventory system I wrote but it contains no code to add inventory to my characters when I start the game. I cleared my cache, and it still happens mostly when starting a new map.

UE5.5.3, Win11, 64GB Ram, 18TB Drive Space, AMD RX580, I7-7700k
Plugins includes Voxel Pro, Ultimate Sky. Character Models by Darby (He does great work), Soon to be adding in Fluid Flux.

ok narrowed it down a little bit.

it is only happening when I use Play from here. I am thinking that UE5.5.3 is not clearing a cache or buffer.

it is only filling the slot 0 of my inventory but on occasions it fills my entire inventory if the amount added is large enough.
