Hi,
I have been having this issue since couple of days.
It seems like all the modern pages in different sites of the environment, the left navigation or quick launch stopped loading.
so i see on the console below error. I seem to not figure out anything.
Any help is appreciated.
ERROR:
sp-pages-assembly.js?uniqueId=xx Uncaught (in promise) TypeError: Cannot read property 'call' of undefined
at t (sp-pages-assembly.js?uniqueId=xx)
Has the farm had any recent SharePoint patches applied? If so, what KBs?
We didn't do any patches since we moved to 2019 last year.

Good day,
Any update on this error? We installed SP2019 with October Patch and we are experiencing the same issue.
Regards,

Seen this issue in two patches the first is August 2020 security update and the second one is Jan 2021 security update.
So if you have installed both above mentioned patches you are likely to face this problem on Sharepoint 2019 modern sites. But the good news is both of them are fixed in the later patches. So if you have installed August 2020 CU and getting the problem just download the October 2022 CU and it will fixed and if you have installed Jan 2021 patch and facing the problem you need to install March 2021 both language dependent and independent patch to fix this issue.
I have written an article on this as well which you can refer : Quick navigation missing on modern sites
Hope the above information helps.
I am experiencing the same issue on SharePoint Server 2019 on-premise; no left navigation, no ribbon / command bar (no edit page button) and errors in console with sp-pages-assembly.
I have installed the latest available CU and Language pack and still have this issue.
16.0.10387.20008 June 2022 SharePoint Server KB 5002212 installed
Update for Microsoft SharePoint Server 2019 Language Pack KB 5002206 installed
PSCONFIG ran successfully after both updates were installed.

We just had the same issue. But as described in the KB 5002212 you also need KB 5002211. KB 5002206 was for the May Update KB5002207
Thank Michael for the feedback.

Perhaps on a system that is WORKING, someone could send / upload a ZIP file for me with the 3 files in question?
I could then compare the file sizes etc.. and replace the files I have to test if it works?
sp-pages-assembly.js
/_layouts/"hive version 15 or 16"/"SP version folder"/next/spclient/en-us/sp-pages-assembly.js
5.sp-pages-navigation.js
/_layouts/"hive version 15 or 16"/"SP version folder"/next/spclient/5.sp-pages-navigation.js
13.sp-command-bar.js
/_layouts/"hive version 15 or 16"/"SP version folder"/next/spclient/13.sp-command-bar.js
I cleared the server cache as well as doing the side by side upgrade option (https://blog.stefan-gossner.com/2022/05/31/trending-issue-left-navigation-missing-after-applying-may-2022-cu-for-sharepoint-server-2019/)
Only after clearing the server cache on all SharePoint Server 2019 servers, did the left nav and the commandbar start working properly.
@Clive Brandon Thanks for sharing you answer.
After doing side by side upgrade option.
could you please tell me how you cleared the server cache? do we have to perform on all the front end servers?
thanks in advance.
@Ashok I have attached the steps I followed (too 218786-clear-sharepoint-server-config-cache.txtmany characters to paste in here)
There are poweshell scripts around that can to this for you but I just used the good ole "manual" option :-)

I had the same problem.
After installing the latest SharePoint Language Pack, the problem is disappeared.

Installation of last CU resolved this problem. I recommend to google Todd Klindt's blog to find the latest available update
Also thanks Anders Dahl for psconfig reminder)
