Hello, I just tried to upgrade 9.1.1 -> 9.2.2.178, and if anyone could point me into a solution to my problem would be greatly appreciated ;-) Thank you in advance!

I got the following error below and I have not many modules installed, went through them all:
Modules:
- Mandeeps, Porto 5, just upgraded to latest 922 compatible (Includes module Live Slider latest version) Upgraded from porto 3 to 5 before trying the DNN 922 update.
- Action Form - Latest version 5.0.153 also 922 compatible, upgraded from a previous version to latest.
- Bulk user manager 3.4.1 also supposed to be 9.2.2 compatible. Newly installed in 9.1.1 before trying the upgrade.

I have uninstalled 1 or 2 unused older modules to be sure they would not interfere.

The error:
