WARNING: 64 repetitive deprecation warnings omitted.

My solution:

Since it seemed to be solely due to bootstrap, I tried implementing the latest version of bootstrap (now 5.3.0), changing assets -> vendor -> bootstrap -> scss

Replacing the entire folder with the new version, so far I am not noticing any problems

After the upgrade I no longer have any compilation warnings

[Gorlenah]

After upgrading bootstrap, the theme does not work graphically correctly, so I migrated the bootstrap version used by this repository.

I had to edit some files manually, but the majority was done using the automatic migration tool.

In my fork there is the fix, waiting for the merge

I have the same issue
