Safari developer tools reset entire browser

I have been experiencing an extremely frustrating, ongoing issue: every time I open the developer tools in Safari, within a minute or two my entire browser session is reset. All my cookies are wiped out, I'm logged out of every website, etc.

I haven't been able to find any way to alleviate this and it makes the developer tools unusable. Is anyone else having this problem or know what could help? Thank you so much
