Hi! Can you try disabling the python environments extension and see if this changes the behavior? Thanks

[mtm-tud]

Hi, thanks for fast response, i had to rollback to 1.104.1 which I've found to be stable (I am lecturing a class of 130 2nd year students, and they have a big assessment over the next 2 weeks so I had to get them set up for success today, most were impacted with the 1.105 release and now all are rolling back tonight). I will attempt to do that on another machine once I get this sorted. Thanks!

[eleanorjboyd]

totally understand- glad rolling back worked and I will look at this on my end as well
