hard drive – Bootcamp partition space disappeared after removal through Bootcamp Assistant failed

I’m running macOS 11.3.1 on my 2013 MacBook Air and wanted to remove my Bootcamp and reclaim the space. Had around 40GB free on my macOS partition and the Bootcamp one was 50GB. So I ran the Bootcamp Assistant to remove the partition – thing is, it froze mid-process and the computer stopped responding, even the curson stopped moving. So I powered it off with the button, powered it on again and now there is neither the Bootcamp partition nor its space anywhere to be seen as it did not get reclaimed by the macOS partition. Diskutil outputs:

The 50GB isn’t visible in the GUI diskutil either. How can I reclaim that space?
