Audacity 2.3.3 issues

Hello, I’m new here but have been using Audacity for my podcast for 11 years now and it’s only in the last two weeks that it’s started causing me enough of a headache to finally consider an alternative.
I’ve recently started using version 2.3.3 after the previous version started giving me issues and since then, every time I’m editing, the tracks have changed to look like this (see attachment).
I’ve never been a tecchy guy so Audacity was just right for me. I could focus on creating the content and for 11 years I’ve been able to get my shows out every week without any major Audacity issues until now. When I click ‘view normal’ I still can’t get rid of this new look, if indeed it’s a new look or perhaps a bug?

Grateful for any advice.
Thanks.

It looks like you’ve (accidentally?) switched to the “Envelope Tool” (https://manual.audacityteam.org/man/envelope_tool.html)
Press the “F1” key to go back to the normal “Selection Tool” (https://manual.audacityteam.org/man/selection_tool.html)
