[DonJayamanne]

Not sure why this change was introduced, however removing this fixes the issue

        const info = EnvironmentInfoService.getInterpreterInfo(env);
        if (info !== undefined) {
            this.cache.set(normCasePath(interpreterPath), deferred);
            deferred.resolve(info);
            return info;
        }

The older versions didnt have it, hence while comparing the code found this difference and tried without it, and bingo.
