Recent update to snapd-2.53-1.2 breaks all snaps

Hi,

yesterday or the day before the version of snapd on my tumbleweed system (x86_64) was updated from 2.52.1 to 2.53-1.2. Since then I cannot execute snaps anymore. Especially bad because the snap version of “teams-for-linux” was the only one working.

Symptoms are:

  /snap/bin/teams-for-linux --chromeUserAgent "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.100 Safari/537.36" --enableDesktopNotificationsHack true
cannot load program:

: Invalid argument

Q1:Has anybody seen this as well?

Q2: where can I find older versions of the packages?

Thanks in advance
Martin
