Home Assistant locks up when copying source code

[cal37 (Allen)]

I have a weird issue, when I try to copy the source code of my card configuration the whole web page locks up and I can’t do anything. Any ideas what this could be?

Same issue on my system. Happens in both Chrome and FireFox.

Took me a few minutes to isolate the issue. Do you have MalwareBytes installed? I disabled MalwareBytes Browser Guard and everything worked fine

Thank you so much for sharing. It appears that this was the issue for me, disabled Malwarebytes Browser Guard for my SSL/https instance of HA and everything is great. Interestingly enough it doesn’t have an issue when accesing HA via http.
