When saving the product (more precisely, changing the number of main items or in combination) with the multistore option enabled (only in the context of all stores), an error appears. Interestingly, after the second or next (how many stores in multi, how many times you have to click) the record goes correctly.
Recreation:
Go to BO >> set the shop context to >> "all shops"
go to the PRODUCTS tab >> edit the selected product >> change the STOCK (QUANTITY) to another >> click SAVE
I get a red message "Unable to update settings." and there is a problem with writing.
I get an error in JS console:
Failed to load resource: the server responded with a status of 500 (Internal Server Error).
There is no error in the NETWORK tab, despite the debugging mode enabled in Presta.

Data for the demo version:
This is the original, freshly installed version.
Only the multistore has been enabled and one demo store has been added. That's all.

You have set your multistore option "Share available quantities to sell" to NO. This means when you are editing the product in All shops context it does not know what to do with your quantities.
