Reaching out for some support, a 3rd party network our users connect to uses the pulse secure app.
has been working fine no issues however I believe the 3rd party have recently updated something and it has upgraded the dshostchecker version as a result this is now crashing across all our machines when attempting to run.
Below output of event log of the app crash.

The version of dshostchecker.exe looks to have been modified on 20/8 build no 22.214.171.12451
Without this running users are not able to connect. To troubleshoot so far we have run windows 10 different versions 1903,1909, 1809 etc without success all have the same issue.
We have even tried a windows 10 vanilla deployment which also has the same problem so belive the issue is with the app itself rather than anything client end specific.
the 3rd party support on this is very hit and miss so reaching out to see if there is any guidance anyone could provide on a possible fix.
@ldstc There is a known issue with 9.1R8 VPN server and cache cleaner policies (host checker), please disable the cache cleaner on the realm/role which are being assigned to the users.
9.1R8.2 code should be having the fix and it's both client & server side fix.
