Builds getting stuck every time

I have the same issue.
I even tried to delete cache before the build command:

[build]
publish = "public"
command = "rm -rf /opt/build/cache && hugo --gc --minify"

Sadly didn’t solve anything.
Deployment is still stuck and can’t go ahead unless you manually stop and click Clear Cache and deploy site

I would also like to point out that there are issues with Hugo versions as well:

You can see it here:

10:15:01 AM: Installing Hugo 0.89.4
10:15:03 AM: hugo v0.89.4-AB01BA6E+extended linux/amd64 BuildDate=2021-11-17T08:24:09Z VendorInfo=gohugoio

However it then uses a different version to build:

10:15:10 AM: $ rm -rf /opt/build/cache && hugo --gc --minify
10:15:11 AM: Start building sites …
10:15:11 AM: hugo v0.85.0-724D5DB5+extended linux/amd64 BuildDate=2021-07-05T10:46:28Z VendorInfo=gohugoio
10:20:22 AM: Canceling deploy

While of course in the netlify.toml the correct version is specified:

[context.production.environment]
HUGO_VERSION = "0.89.4"
GO_VERSION = "1.17.3"
HUGO_ENV = "production"
HUGO_ENABLEGITINFO = "true"

I only have two plugins installed:

[[plugins]]
package = "@netlify/plugin-sitemap"

[[plugins]]
  package = "netlify-plugin-submit-sitemap"

And I had the very same issue even BEFORE when I had many plugins.
I went over in the last weeks and deleted all of them but these two.

Can you help us? It’s getting very annoying having to go to the pipeline and make sure it didn’t get stuck at some point again.
