I had the same problem while using node (any of the 16/stable, 18/sable, 20/sable). I started having this issue after enabling snap parallel instances (running more than one version of a package). After I've disable the option everything was working as expected. Note that you might need to remove the parallel versions of packages that you have already installed.
Check if this option is enabled on your end:
```
sudo snap get system experimental.parallel-instances
```
and disable it:
```
sudo snap set system experimental.parallel-instances=false
```
